I know. I feel sometimes that he doesn't care, he doesn't compliment me as much, talks about getting a new girlfriend (but when I confront him about this, he says he's only kidding and he would never break up with me so i shouldn't worry), and he gets mad easily.

Say something nice to me one second - I'm happy. Joke around like that I get kinda down. Say something nice - Happy. Is that bi-polar or just being normal? Or being depressed? Or should I not just get upset and change my mood like that and not take it so seriously?

But sometimes I think well he does care -- he wants me at his track meets (which I can't always make), has a collague of notes/pictures/cards I gave him in his room, writes me notes, and makes plans with me.

Sometimes I think he acts ways I don't feel he cares since he gets stressed. Then I get depressed, then I feel he get mad when I'm depressed then I feel I'm weighing him down and ruining his life.
