How do I handle a boyfriend who always tells me that if I don't straighten up then he's going to find someone who's better than me? I mean, better than me?! How do you feel about that? He's constantly teasing me with it, even at times being serious with the notion. I can't handle myself with this kind of a crisis and he understands how I feel. He doesn't really care about that. He just wants to up and leave me and find someone better. It's seriously driving me nuts.
