Welcome to Gaia! ::

My boyfriend is being absolutely horrible lately.
He is normally cute, sweet, super smart, we talk forever about movies or books or he'll sing me songs. We live about an hour away from each other, so we don't get to see each other much since he hasn't gone to get his permit yet (he's 21). Every once in a while, he gets into a bad mood and gets bitchy, but normally he'll apologize and be fine again in a few days.
But now, he's pushing me away and being horribly rude. He told me that he was having issues at home, and promised me that we'd talk about it, since he was taking them out on me. But I called him like he asked and he refused to talk about it. He's been miserable for about a week and a half now, and every time I think that he's getting better, he winds up pushing my further away suddenly without explaining why.

I just don't know what to do.
I told him that I'd give him some more space, so he can deal with his problems, since he doesn't want my help.
And he kept telling me that I could so much better than him and he hates hurting me but keeps doing it because he doesn't want to hurt me anymore. Which makes no sense to me. Basically I think he wants me to leave him so he can be miserable in peace. But I love him deeply and don't want to leave him, especially when he's hurting like this.
