It Meant Something to Me

"Look, what happened between us was important to me, and I thought it meant something to you too. But clearly Elsa means more to you than I do."

- Alejandra, La Verdad Oculta

Alice and Bob (though gender reversals are common here) have decided that they want to pretend to be a couple to make their exes jealous, or pretend they're Happily Married to make sure Bob isn't deported, or decide that sex doesn't need to have an emotional attachment and become Friends With Benefits.

It all goes along swimmingly, until Bob starts feeling something for Alice. It can start by finding out she and he are very compatible, or as a jealous Green Eyed Epiphany when she goes off with a boyfriend or has sex with someone else. Eventually, their perfect arrangement starts to fall apart as the ground rules are broken, leading to a confrontation.

Alice may or may not have feelings for Bob, but even if she does she'll defiantly say that their time together "meant nothing to me", to which Bob will plead his love with "It meant something to me, dammit!" This might be substituted with "I felt something!" and "I felt nothing!" Of course, Bob will storm off heartbroken that the woman he loves has just shot him down like a World War One observation balloon.

If Alice really doesn't have feelings for Bob, then it's heartbreak time (happily, Bob will likely come to realize he's been thoroughly neglecting Claire and hook up with her). If she does, she's likely been denying her feelings, something another character will have to spell out to her very plainly before she realizes she loves Bob, and goes after him seeking forgiveness.

Anime and Manga

 * Pretty much a given in Shoujo romantic drama animes. Especially if there's a Love Triangle or something to that effect.
 * Occurs often in the manga/anime Peach Girl.
 * Flay and Kira in Gundam Seed. Kira did like her, but when their relationship started she was definitely in Yandere mode, so she failed to realize that she did love him until it was too late. By the time she gets her emotional issues sorted out in that department, and it just goes downhill from there for her.
 * Yu-Gi-Oh has one of these, in an indirect and implicit way in episode 90, when Mai asks Jonouchi/Joey whether she was in the dream he had of all his friends after he's knocked out by a bolt of lightning caused by Odion in episode 89, at which point Joey gets shy/flustered and lies to her. This could arguably be said to have
 * Note that in the manga, Jounouchi wasn't lying at all,
 * In Devilman,  betrays Akira and leaves him with an impression that their friendship was just a lie. not only it isn't true,.

"Ernie: Happens to me at least once every party. Some guy comes up to me and says "Thank you for making this happen... I needed this. This really meant something to me." And they nod... and I nod back."

 * Tearfully "I swallowed your cum. That means something!"
 * Can't Buy Me Love, and its remake, Love Don't Cost a Thing.

 * After having sex, the titular characters of Zack and Miri Make A Porno feel something for each other. Zack is the first to admit it, with Miri denying she felt anything because she thought Zack had sex with another actress and didn't reciprocate her feelings... and then Zack leaving, because he thought Miri had had sex with one of the porno's actors. This may be a theme in Kevin Smith's films.
 * ...Isn't the entire point of a porno for the actors to screw each other?
 * The walk outs were over assumed after porno "just for fun" sex. So they probably viewed it as "He/She doesn't care about me at all since he/she is screwing with the other actors off the job!" If memory serves, neither had sex with the other porn actors off camera.
 * In Life as We Know It, Holly and Messer are forced to live together like husband and wife and raise their goddaughter after her parents die. Of course, they hate each other, but grow to like each other. After it gets too serious, Messer leaves for a job in Phoenix. He comes back for Thanksgiving, after which Holly gets with Sam.

"Leo: "WHAT?!""
 * Cordelia (or maybe not) was later on the other side of this equation with Connor.
 * This is various played straight, averted, and subverted in layers on Chuck between the title character and his CIA handler Sarah, who pretends to be Chuck's girlfriend as a cover for most of the first two seasons. This trope contributes a central part of the drama of the show.
 * Chase says this to Cameron in House and she immediately breaks up their "friends with benefits" relationship, claiming that she warned him not to fall in love with her. She did explicitly warn him and she does end up marrying him, at least for at time before
