Could I get my ex boyfriend back?

I started dating my boyfriend in November of 2008. We dated for a year and for the most part everything was perfect. We spent all of our time together because that's what made us happy. We had so much fun together. We were inseparable. That is, until he went off to college. He went to college and then starting having less time for me. He went out of his way to come see me as often as possible and he picked me up on the train so I could go spend the night at his dorm etc. Things were still amazing when we were together but when we talked online or over the phone things would sometimes go downhill. We'd fight about things like him being out too late and us not having enough time together or over things more stupid than that too. The fights would sometimes end with one of us saying things like "You know what? I'm so sick of this! It's over! Goodbye" but then we'd always come back whether it was a few minutes later, an hour, or the next morning. We'd be like "I'm sorry. I didn't mean it. I need you." Then everything would be fine again until the next fight. So in November of 2009 he told me it was over and he seemed to mean it this time. I was a wreck. It really was over. I begged him to come back and he told me "it's over. i'm done. get the **** out of my life!" and i was miserable. It wasn't like him at all. A few weeks later we hung out and he acted like we were still dating by calling me "Babe" and being touchy etc. Then when I asked him what that day meant he said "Nothing we're friends." I was like "Friends don't act the way you acted today" and he flipped out on me. Anyway, eventually we became good friends. We talk all the time, he tells me everything still as far as I can see. He told me he still cares A LOT for me. He told me he doesn't want me to move on. He gets jealous when I hang around other guys etc. But he still insists we're just friends. He said he can't handle a relationship right now. "It's too much for me" he says. The thing is he wont tell me if he still loves me just that he cares and he wont tell me if there's hope for us. Every time I ask him anything his answer is always "I don't know". He confuses me. Oh, and he tells me how y I am and how he has ual dreams about me and how he wishes they were real. But he was never the kind of the guy who cared whether he had a ual relationship he was happy just being around me. Of course we did things but it was never required for us to be together so I don't know. He said he wishes we could do those things but that we can't because he can't have a relationship with me. I'm so confused. I don't know what he feels or what he wants. Does anyone have any advice? Could I get my ex boyfriend back?
