I've told him how I feel too (not the exact words "I don't like you" but I think I criticize him enough for him to get the point!) and he just won't change. He is who he is, he says. If I don't like it, there's the door. I can't find anything that's quite worth leaving him over though. He says he thinks he has changed, but sometimes I feel like it's for the worse. I'm just tired of trying to figure him out. He'll be super nice one minute and the next he's completely insulting, and he can't figure out why I've kind of given up. I'm just tired of playing that game.
After I re-read this, I realized the last couple sentences probably describes how he feels about me, too.
