"Okay. For the last time. "I, Anya, want to marry you, Xander, because... I love you and I'll always love you. And... before I knew you, I was like a completely different person. Not even a person, really... and I had seen what love could do to people, and it was... hurt and sadness. Alone was better. And then, suddenly there was you, and... you knew me. You saw me, and it was this... thing. You make me feel safe and warm. So, I get it now. I finally get love, Xander. I really do.""
