Mad Love



"Moze: Why don't you just tell Missy that you're not interested in her? Ned: Because the truth doesn't work on crazy people!"

- Ned's Declassified School Survival Guide

Unrequited Love can hurt. A lot. That is, of course, assuming that the target of all those squishy pink emotions is unaware of them and the sender is painfully aware of this. Sometimes, though, the roles are reversed. The object of affection not only is perfectly aware of this one-sided crush, but actively tries to tell his erstwhile Love Interests that he isn't interested. Sometimes violently. The Love Interest, meanwhile, fails to get the very clear message, to the point that they go past mere Clingy Jealous Person and become what any sane person would consider a Stalker with a Crush, or a Psycho Supporter if they honestly mean no harm to the other party and also respect their ideas.

If the crazy person has terrible taste in suitors, then the "hubby" or "wifey" will abuse that unconditional love for use in their crazy schemes, and never hesitate to betray them if they fail, or if they get too whiny. Y'know, because whining can cause headaches and stuff. And of course, the innocent (or more like oblivious) kid will come trotting back for more punishment. If the kid has two neurons, they'll think their hubby/wifey has a "funny way" of showing love. If they have more than three, they'll realize that Mr. Troubled but Cute or Miss Broken Bird is just plain trouble and move on to someone else, trying to resist falling back to them.

Expect this person to be a headache for anyone in the center of a Love Triangle or Love Dodecahedron. Third parties trying to convince them they should move on will face replies like "You're Just Jealous" and other psychological barriers to reality and sanity.

This can happen to people of BOTH genders. It's more common to have females in the role, but it's not unheard of having males playing the part. Only that a female is more likely to be pitied, but a male will frequently become a Butt Monkey.

Compare with the more serious Love Martyr, whose unconditional love is presented (or at least intended) as genuinely selfless and noble instead of crazy, funny and/or stupid. Compare Minion Shipping and Unholy Matrimony. Further compare with Yandere. Contrast with Vitriolic Best Buds, where this involves friends. For Bonus Points, throw in some moments of affection going the other way, leaving watchers REALLY wondering what's going on.

Anime and Manga

 * Full Metal Panic!: Gauron "loves" the beautiful Kashim he first laid eyes on all those years ago, the same boy who hates him and loves to beat the shit out of him.
 * Though knowing Gauron, he probably loves it more that Kashim hates him and beats the shit out of him. Whenever Sousuke displays docile tendencies and sort of "gives in" (like in TSR, where he gently told Gauron "please"), Gauron gets pissed off and acts like it would've turned him on a lot more if Sousuke were acting violent and defiant.
 * Comedic example found in Girls Bravo. Yukinari, Kirie, and Koyomi are wanted by the perverted Lisa, Kosame, and Fukuyama. All the punches and various other acts of rejection they dish out? The Fukuyama siblings, plus Kosame, like it very much.
 * Code Geass
 * It can be argued that Rolo is like this in regards to Lelouch, who even flat out tells him at one point that he's simply using him.
 * And Mao displays even more clear indication of this for C.C. He is so completely in love with her that he thinks it's alright to cut her up with a chainsaw in order to run away with her.
 * Outlaw Star: Melfina is terrified of Harry for his unhealthy obsession with her and wants nothing to do with him. Rather than drive him away, her rejection of him simply makes him even more determined to win her love.
 * Ranma ½ has multiple.
 * Tatewaki Kuno is after both Akane and Girl-form Ranma. Neither rain, nor snow, nor repeated knocks into the stratosphere will deter him.
 * His sister Kodachi also partially qualifies for her pursuit of boy-type Ranma, but before the end of the manga admits that she knows he doesn't love her. Note that this doesn't actually stop her.
 * And of course, one must mention Mousse, who pursues Shampoo past all common sense...
 * And Shampoo, in her pursuit of Ranma.
 * Ryoga almost qualifies in his pursuit of Akane, he's just smart enough to hide it and take the stalker route instead.
 * Nemu Kurotsuchi of Bleach puts up with the abuse and humiliation of the sadistic Mayuri Kurotsuchi, her father, because of her love and admiration for him.
 * The Yandere Misa Amane of Death Note will gladly do anything, including kill others or sacrifice herself, for Light's sake after he kills the murderers of her parents. Light sees her as an annoyance but one that can be easily manipulated, so he plays along, albeit considering killing her quite calmly at several points,
 * Considering the blonde hair and the fact that she held a lucrative career before becoming the second Kira makes her seem like an anime version of Harley Quinn (especially considering Harley's new outfit in Batman: Arkham Asylum).
 * Point of interest: previous to seeing him, she wanted to meet Kira who had avenged her parents and maybe work with him, but was also open to killing him if necessary, and remarked "I've got the eyes, so I'm stronger." She also plotted quite coldly and cheerfully at this period to kill Rem because it would be more convenient, even though Rem, unlike Ryuk, had no intention of hurting her. Then she saw Light, fell in love with him, and lost all traces of real personality. For some reason Psycho Boy is irresistible to women, and Psycho Girl is incredibly attractive to shinigami.
 * Ryuk is the shinigami psychopath, but he doesn't seem to be irresistible to anything. Except maybe psychos?
 * Yubel in Yu-Gi-Oh GX is not above murder, manipulation, kidnapping, torture, and even brainwashing and assaulting its own love interest Judai so they could be together. In an unusual twist, Yubel also makes itself out to be the Love Martyr, encouraging Judai to do the same despicable things to it, under the crazed belief that since "true love" is sharing emotions and experiences - both good and bad - love can only be expressed through shared suffering.
 * Itsuki from Yu Yu Hakusho. May be subverted in that.
 * The only one of the seven Sensui selves Itsuki seemed to think he had any romantic mileage with was the girl. Which, yeah. All of him liked having Itsuki around to help out, though.
 * Vampire Princess Miyu has
 * Haru towards Tsuna in Katekyo Hitman Reborn. Interestingly, she started off hating Tsuna because she thought he was mistreating Reborn, but quickly changed her mind after he saved her from drowning. With a little help from a Dying Will Bullet, of course, but that was enough to rewrite him as "awesome" in her book.
 * Chrome for Mukuro. Of course Mukuro does seem to love her back in his own twisted way.
 * Axis Powers Hetalia
 * Russia beats and stalks Lithuania, the only person he seems to be truly happy around. Considering that Russia is a male Yandere... well.
 * His sister Belarus is quite similar. Lithuania seems to have a crush on her, she agrees to go out with him once... and ten minutes later, she breaks and twists his fingers. Then, she's shown as Russia's Stalker with a Crush... Must be In the Blood.
 * Belarus and Russia also qualify. He constantly cries, hides, and tells her to "go home!", but that doesn't stop her from literally breaking down his door wanting to "get married, married, married!"
 * Rurouni Kenshin
 * A tragic take on his is the relationship between Shishio Makoto and Komagata Yumi. She was his retainer and caretaker, always frustrated because she wasn't an Action Girl and knew battles were the more important thing that her Magnificent Bastard boyfriend cared for, so she didn't mind even  And Shishio actually cared for Yumi as much as someone like him could, defending her when a shocked and horrified Kenshin questioned what had just happened
 * They go take over Hell together afterward! It's sweet! (No, really. This happens. They wait for Hoji, his administrative assistant with a man-crush, to commit suicide and catch up with them, too.)
 * Kamatari had it even worse, though I don't think either case with Shishio really applies—he was quite happy to have them around, he's just All Take and No Give.
 * Kamatari had it even worse because he's a crossdresser and gay, though hardly gender-queer at all (he laughs and flashes Misao when she mistakes him for a woman), and is perfectly aware that he's not the strongest or the most beautiful retainer, and can't compete for Shishio's attention on either field. Even if Shishio liked guys, he'd still probably go for Soujiro. Ow, Brain Bleach please.
 * Fans theorize that Kamatari probably has a past in Kabuki as an onnagata somehow. Onnagata sometimes also worked as high-end call boys, for the right fans.
 * Shishio's good looks are utterly ruined by hideous full-body burn scars, but this doesn't appear to put off either admirer. Maybe that's because despite being horribly Covered in Scars (and he wasn't THAT bad-looking when in full shape), the dude is also damn smart and charismatic.
 * Ladd Russo and his fiance Lua in Baccano! share quite the odd romantic relationship, what with Ladd being a delightfully Ax Crazy Psycho for Hire and Lua being an oddly serene masochist. To them, "I'll kill you last", means "I love you."
 * Specifically, "I'll kill you last" as in "I'm saving you for last because I'll enjoy killing you the most."
 * Yuno Gasai of Mirai Nikki. She'll do anything to be with her Yuki-kun. "Anything" including suicide, homicide (with an axe), stalking, etc.
 * When he told her he reciprocated her love, she responded by tying him to a chair and keeping him drugged, to ensure that he'd stay faithful.
 * It is worth noting that, despite being as reasonably sane as is humanly possible while also being capable of massacring orphans (It Makes Sense in Context), he's still with her after escaping from the chair.
 * In Black Cat, Creed is crazy about Train. Train constantly tries to beat him off of him, and attempts numerous times to kill him. And Creed just can't seem to take a hint. Train must be resisting because someone "evil" is influencing him... and that person must be killed.
 * Digimon: Mummymon is head over heels in love with fellow villian Arukenimon, even though she clearly isn't interested. Subverted somewhat in that neither of them are particularly crazy, and she's willing to tolerate him unless he gets too touchy-feely.
 * Backstory of Umineko no Naku Koro ni in a nutshell, at least as Beatrice tells it - man summons witch, man falls in love with witch, witch doesn't love him,, man can no longer see witch, man decides to kill entire family in order to revive witch and spends most of his time screaming at the sky. Love? Depends on your definition, but definitely mad.
 * from Prétear wavers between this and Love Martyr. On one hand, he's genuinely selfless and wants to help the girl he loves. On the other hand, the girl he loves is a Dark Magical Girl that doesn't care about him, and he's willing to destroy the world to stay by her side.
 * Eva Heinemann from Monster 'fails to get the message' to the extent that her ultimatum to her love interest, after he rejects her very plainly, is the following: facing murder charges which she will lie through her teeth to corroborate, or being with her. That Tenma chooses the former is a good indicator of how batshit crazy she is.
 * More of an inversion though. Eva has no illusions that she is actually in love with Tenma; she only wants to be with him because her life went down the crapper after she dumped him for no good reason, only to realise much later after a string of bad boyfriends (one a homicidal lunatic) that Tenma was probably the only one who actually cared for her. Her rationale swings between a consciously doomed attempt to recapture that love, and more usually a resolution that, if she has to suffer, Tenma must suffer with her.
 * Black Butler
 * Hannah for Alois. No matter how much he hurts her, she wouldn't think of leaving him, since she absorbed Luka's love for him.
 * Also Grelle for Sebastian. Leaving the fact that she's a male-to-female Transsexualism (coming from Word of God, and here's the proof), she has a tendancy to do anthing to get Sebastian's attention. This makes her useful for the other main characters, especially Ciel, who promises her alone time with Sebastian in return for help. Sebastian does not seem too fond of this idea when he finds out, and as far as the anime shows, he manages to avoid her. Oh and did we mention she's a death god and Sebastian's a Demon? Yeah, this a very strange relationship indeed.
 * Grelle has it for William too.
 * Saint Seiya: Pandora with Hades.
 * Trigun features poor Legato Bluesummers, Axe Crazy telepathic mass murderer. He doesn't have it so clearly bad in the anime, though he is utterly devoted and Knives sends him to his death, but manga Legato...alas, poor monster.
 * The fact that Knives doesn't care about him is sad. The fact that he is perfectly aware that after trying to have Vash killed any chance of Knives ever liking him is gone, is very sad. The fact that despite how shittily Knives treats him no one else ever treated him nearly as well is just tragic.
 * Like the Rurouni Kenshin example above, this Big Bad's minions include two who are madly in love with him. Also, much blood and horror, and Legato is totally unhinged for most of Maximum.
 * The trying-to-eat-a-steak-while-voluntarily-in-a-bondage-straitjacket thing was funny, though, in a horrible way.
 * Uh...wasn't that after Knives broke his spine for trying to Murder the Hypotenuse while Knives was in his healing vat?
 * Every single relationship in Durarara!! is like this, mostly due to the incredibly dysfunctional cast. The healthiest one is probably the relationship between a back-alley surgeon and a female Dullahan (that is, a woman with no head), where the former outright says that he dissembled about the location of the latter's head because he never wanted her to leave him. And that's the point where their relationship improves.
 * Ox towards Kim in Soul Eater.
 * Prince Diamond and Ali towards Usagi in Sailor Moon and Emerald towards Prince Diamond.
 * Shuichi from Gravitation towards Yuki. He chases Yuki constantly, despite being rejected, verbally abused, and often being called a little brat. They eventually end up together.
 * Gintama: Ayame "Sa-chan" Sarutobi actually enjoys being abused/rejected by the object of her affection Gintoki.
 * Quite a few relationships in Pandora Hearts are like this, like Jack for Lacie, Oz for Alice, Vincent for Gil, possibly even Gil for Oz...
 * In Inuyasha, Inuyasha found himself on the receiving end of Jakotsu's attentions who was quite determined to show Inuyasha the affection he always gives to his favourites... which involves death and possibly torture/rape.
 * Zetsuai1989: Kouji for Izumi.

Comic Books

 * Harley Quinn and Joker, of course. The one shot comic Mad Love, which was later adapted into an episode of the same name, that tells how Dr. Harleen Quinzel, then a psychiatrist at Arkham Asylum, first met The Joker. The Joker saw her immediately as a tool to be used, and manipulated her into becoming a henchmen. However, at the climax, Joker tosses Harley out a 3rd story window for getting the upper-hand on Batman without him, and he blames her because she "didn't get the joke". Cut to Arkham at the end of the episode with a heavily-bandaged Quinn vowing in her normal voice that her life of crime was over since she now saw the Joker for what he was: "a murderous, manipulative, irredeemable -" At which point she spots a rose sitting in her cell with a note of apology from Mr. J, causing her to smile and dreamily say "Angel!" in Harley's voice. Definitely chilling, and worth a watch. Even more so in the comic, Dr. Leeland asks Harley what it felt like to be treated so poorly after all she's done. Harley notices the rose and says "Like a kiss" which is all the more disturbing. According to Bruce Timm, The Joker really does need her, saying, "Everyone's seen The Joker laugh. Harley is the only one who's seen him cry."
 * You can see it too, when she runs off with Ivy, the man can't even find his socks.
 * At one point, after yet another incident when the Joker nearly kills her, Ivy freaks out in frustration and demands to know if Harley understands what just happened, and Harley tells her that yes, she knows he was trying to kill her.
 * An old example from the funny pages occurs in Krazy Kat. The eponymous character has a crush on Ignatz Mouse, and regards the bricks he pelts at her as signs of affection: "Little dollink -- always fetful!"
 * Mr. Gosh from Lenore the Cute Little Dead Girl takes Mad Love to a whole new level, as the eponymous Lenore frequently kills him in response to his interests—he incorrectly writes it off as more of her typical fatal accidents, when he's one of the few people she intentionally tries to kill. Then again, as Lenore is a 10-year-old girl who died roughly a century prior to the start of the comics, the Mad Love may be the least disturbed part of his interest in her.
 * In the newspaper comic strip Curtis, Curtis Wilkins considers the snobbish and aspiring actress Michelle to be "my girl," despite her going to great lengths to avoid him (and when she doesn't, it's only to brag to him about her accomplishments or have him do some menial task for her). Even after Michelle flat-out states to him that she's tried every way she can think of to show that she's not interested in him, Curtis believes that she's only being a good actress, causing her to sob in frustration.
 * Terra's and Beast Boy's relationship is hilariously flanderized into this in Tiny Titans. Beast Boy is head-over-heels in love with Terra, however Terra loathes him and his affections. It goes way past being annoyed at his love-sick behavior, she's constantly pelting him with rocks and berating him.
 * The Captain America (comics) villains Red Skull and Mother Night had a relationship like this. Mother Night was deeply in love with the Skull, even though he was always abusive to her. At one point he even started flirting with Viper(Another Cap villain) just to piss her off.

Fanfic

 * Nana's Everyday Life, if it didn't cross the line so many, many times it would be Glurge-y.

Film

 * Mrs. Lovett in Sweeney Todd: The Demon Barber of Fleet Street, who enables Sweeney's serial murders and disposes of his victims by baking them into pies. She continues to make romantic overtures to him despite his obvious disinterest, going so far as to.
 * The classic film Mad Love (a remake of the Conrad Veidt film Hands of Orlac) is a borderline case at best. Dr. Gogol loves the beautiful actress Yvonne, and knows she is happily married to her husband. He settles for trying to drive her husband mad in the hope of picking her up on the rebound.
 * Serves as The Reveal in He Loves Me... He Loves Me Not.
 * Rocky Horror Picture Show's Columbia falls under this. She's hopelessly devoted to Dr. Frank N Furter despite the fact that he views her as nothing more than his "groupie". This is later subverted when Columbia finally realizes that Frank doesn't give a damn about her and totally chews his ass out for it.
 * This is driven even FURTHER in the original play in which Columbia does a Heroic Sacrifice by putting herself between Frank and Riff Raff causing her to be killed by the laser. Frank's reaction? "Stupid bitch." Though, he does say it in a way that hints that he did feel somewhat sorry for her.

Literature

 * In Second Apocalypse develops a very twisted sort of love/obsession with  who wants nothing to do with him.
 * Bellatrix Lestrange in Harry Potter embodies this trope. She's as mad as they come, and her devotion to Voldemort is nothing short of obsessive.
 * Wuthering Heights - Edgar for Cathy Earnshaw. She walks all over him, ignores his wishes, throws temper tantrums and obviously prefers the company of Heathcliff, and yet he refuses to give her up.

Live Action TV
"Trickster: For me? Gee...after I treated you like dirt...hung you out to dry... Jinx: I love you...madly. Trickster: Oh, darling, it won't work. I'm no good for you. Besides, how can I miss you...when you won't go away? *pushes Jinx out of a moving vehicle*"
 * Oz: Chris Keller is all too willing to do anything to keep Beecher for himself, even though this is what drives Beecher away and eventually kills Keller. Their relationship is quite tragic and fucked up, to say the least.
 * Christian Troy and Kimber Henry on Nip Tuck: in the very first episode, shortly after they've slept together, he strips her naked and covers her in red lipstick to mark the places where he thinks she could use a little surgical tweaking. She comes back. Enough said.
 * In Two and A Half Men Rose just won't take a hint from Charlie.
 * Nurse Christine Chapel in Star Trek: The Original Series had an irritatingly persistent mad crush on Spock, despite his overt rebuffs of her. Subverted in an episode of the Animated Series in which Spock and Chapel are affected by a "Love Potion" which, when it wears off, leaves them despising each other.
 * In The Flash TV series, Mark Hamill's Trickster character seems rather like a dry run for his Joker performance, to the point of having his own Harley Quinn, an unstable thrill-addicted toy designer who calls herself Jinx:


 * This was, in fact, the role that got him considered/hired for the Joker.
 * Ned's Declassified School Survival Guide: Missy towards the titular Ned.
 * True Blood: In "It Hurts Me Too" after Bill pins Lorena against a wall and tells her that he'll never love her, she kisses him. He does not react well to this, first going for her throat with his fangs, then responding to her urging him to make love to her by doing so extremely violently to the point that he leaves several cuts on her chest and twists her head around 180 degrees. Lorena loves every second of it, and dreamily says "Oh William, I so love you." Also, even after Bill tells Lorena multiple times that he hates her guts and can't stand the sight of her, she still has the nerve to ask him "When will we see each other again?"

Music
"Oh yes, you can kick me /And you can punch me /And you can break my face /But you won't change the way I feel /'Cause I love you."
 * Potentially, "Just the Girl" by The Click Five is about this.
 * "Is It Really So Strange?" by The Smiths.


 * Muse's "Space Dementia" ("You make me sick/Because I adore you so"; "You make us wanna die/I cut your name in my heart/We'll destroy this world for you/I know you want me to/Feel your pain"). Pretty creepy.
 * Eminem and Rihanna's "Love the Way You Lie". Bonus points when you consider both were on different sides (giver and receiver respectfully,) in different Mad Love relationships themselves.
 * See also "Love the Way You Lie Part 2," which is largely the same song, but told more from the opposing point of view.
 * Will Smith's "Loretta" is about a real-life stalker of his (supposedly).
 * Lady Gaga: This is (supposedly) the theme of the song "Bad Romance".

Theater

 * In A Midsummer Night's Dream, Helena is this way about Demetrius, despite the fact that he repeatedly threatens her. Pretty soon, application of Love Potion makes both Demetrius and Lysander fall in love with Helena, which leads to her angrily fending off two guys, convinced that she's being made fun of. In the end,.

Video Games

 * The less-common male version occurs in Tales of Symphonia: Dawn of the New World with Alice and Decus, with the former utilizing the latter's feelings for all they're worth. Of course, that all changes when
 * It's hinted in Pokemon Diamond/Pearl/Platinum that Mars (and possibly Jupiter too) of Team Galactic are on the team due to an infatuation with Cyrus. Since Cyrus considers all emotion burdensome, you can guess how much he returns these feelings.
 * In Episode 3 of Phantasy Star Universe it is greatly implied that the reason Helga is so intent on serving Howzer, even after he deemed her as "expendable," is because she is in love with him.
 * Tira from the Soul Series is absolutely devoted to Nightmare. The scary thing is that this might be her least disturbing trait.
 * Shrowdy von Keifer, villain of A Vampyre Story, makes a habit of kidnapping young women and then "disposing" of them when he gets bored. By the time the storyline proper rolls around, Mona is but the latest in an ever growing line of women who have disappeared that way, and on top of that, she's either the woman Shrowdy's been looking for, or due to be axed at any minute, because she's lasted longer than any of her predecessors. Just for added creepy fun, it's very strongly implied that Shrowdy's victims are all chosen because they resemble his missing mother.
 * There are hints that Carmilla from the Castlevania series feels this way towards her master Dracula. Dracula seems to be indifferent, but Carmilla worships him and does everything in her power to aid him in leading humanity into darkness despite showing no true hatred towards humans.

Visual Novels

 * Moran for M in Shikkoku no Sharnoth. Interestingly enough, they're both portrayed sympathetically.

Web Comics

 * In Order of the Stick, Tsukiko is in love with Xykon, but he obviously doesn't return her feelings

Web Original

 * The Pucca/Garu romance in the webcartoon and television cartoon Pucca has many elements of this, although in this case, it's not necessarily the love that's unrequited, just the interest in displays of affection. Garu does care for Pucca, but he's still not past the "Girls Have Cooties" stage and his girlfriend is a huge Clingy Jealous Girl.
 * Suicide for Hire has had a few of these, first with a crazed stalker who, upon realising she had over 9000 competitors for her target's love, decided to drag his reputation through the mud to ensure she was his only choice; then, later on, there was a woman, who even after having her scalp ripped off and her baby forcibly aborted, a la Jigsaw's wife, still goes back to her husband.
 * Justified in that the second woman was suffering from Domestic Abuse-induced Stockholm Syndrome - she knew she shouldn't go back to him, but he'd cut off every other contact in her life so that she couldn't see any means of successfully escaping him.
 * Shannon from Echo Chamber in regards to Tom.
 * If it was set in the real world, The Nostalgia Chick's obsession with Todd in the Shadows would have either landed her in jail or a mental asylum.

Western Animation
"Smithers: People like dogs, Mr. Burns. Mr. Burns: Nonsense! Dogs are idiots. Think about it, Smithers: if I came into your house and started sniffing at your crotch and slobbering all over your face, what would you say? Smithers: *pause* If you did it, Sir?"
 * Harley Quinn and the Joker, again: All throughout Batman: The Animated Series (where Harley originated, after all), she loved him unconditionally and madly (in the insane way as well as deeply). She would quit him every so often and join up with Poison Ivy, but would go work for him again in the end. See Comic Books for the deconstruction about Harley's origins, which gives her Hidden Depths. (Harley was originally just a Mook du Jour but became an Ascended Extra.)
 * Batman Beyond had a similar case with the supervillainess Inque and a random sap named Aaron Herbst who supervised her while in prison. Aaron ends up requesting to be given shapeshifting powers like Inque, to which Inque responds by giving him only half the treatment, causing him to mutate into a liquedated, powerless blob, and in the end being on the receiving end of this trope.
 * Ed, Edd 'n' Eddy has the Kanker Sisters extreme romantic pursuit of the Eds.
 * Pepe LePew from Looney Tunes. The clawing, the biting, the beatings, the screaming and running away? He's confident that the object of his desire is just "playing hard to get."
 * Penelope Pussycat, Pepe's reluctant love interest, has shown on three separate occasions to be way more aggressive and passionate than Pepe.
 * In a similar vein, there is also Fifi LeFume from Tiny Toon Adventures who chases after any potential skunk boyfriends (or more to the point, male dogs or cats that have white stripes down their back and were doused in black paint).
 * Speaking of Tiny Toon, how about Elmyra? One may think she certainly qualifies, though in a zoophiliac version of the trope.
 * Incidentally, those shorts that show how much of a spitfire an interested Penelope can be suggest that Pepe's scent is literally the only thing driving her away; sad, then, that Pepe is intimidated by assertive women and rapidly loses interest as soon as one or both of them does something to take his smell out of the equation.
 * The Simpsons gives us Mr. Smithers, who only has eyes for Mr. Burns.

Real Life

 * Nathan Leopold, who was willing to engage in criminal acts of an escalating nature as long as Richard Loeb (who was more successful socially, better liked and better looking- as well as sociopathic) had sex with him. (Then again, Nathan wasn't exactly an innocent either, considering that the sex in question tended to be simulated rape.)
 * Lynette Fromme served 34 years in prison (released August 2009) for trying to assassinate U.S. President Gerald Ford because she thought it would make Charles Manson happy.
 * In the Stephen Sondheim musical Assassins, during her part of a duet she croons "You are wind and devil and fire/Charlie/take my blood and my body for your love/let me feel fire, let me drink poison/tell me to tear my heart in two/if that's what you want me to do..."
 * Victor Neuburg. He and Aleister Crowley engaged in a "sadomasochistic magical working" (with Crowley being very much the 'sado'), during which time Crowley was a horrible racist to Neuburg and "leveled numerous brutal verbal attacks on Neuburg's family and Jewish ancestry". They were lovers by the end of the year, if not sooner. Then Neuburg had a nervous breakdown.
 * The documentary Crazy Love documents the real-life (and pathetic) Mad Love between Linda Riss and Burt Pagach. After the two had an affair (which Riss ended), Paguch hired men to throw lye in her face. He went to jail, but Riss dumped her fiance (who still wanted to be with her after the attack) and married Paguch after he got out. Certainly brings new meaning to the phrase "severe co-dependence".
