Men are not complicated. He broke up with you for what ever reason. But it sounds like he is still getting every thing from you he got before ( emotional support, friendship etc -(it doesn't sound like you were having a physical relationship -- which you should not be at your age)) but now he doesn't have to commit, to be your boyfriend. That way when some cute college girl comes along, he can just go out with her, and go "What? we were just friends, I don't know why you are so hung up." Or what ever kids these days say. He is using you as a security blanket until his next, college life kicks in. I don't mean to say this is a bad guy or he is deliberately deceiving you, but you are making it easy on him. If he wants you, make him say it. If he doesn't -- cut him off. You are worth more than getting strung along. Get on with it, there is a boy out there who wants to be with you.
