He doesn't want a relationship right now..?

Gonna be a long post, I’m sorry! I hope you can help me. I met this guy in April through some friends because he’d been ‘stalking’ me for a few weeks and wanted to meet me. At first I wasn’t really interested, but we started talking and I liked him. We kissed for the first time in June and started a ‘casual’ thing, giving that I’d never been in a relationship and he had JUST got out of a long one and also ‘cause we wanted to figure out what we had before jumping in a relationship. The thing is we felt really attracted to each other so everytime we were together, something sexual happened – not intercourse though. I’m studying in his city, so by the end of June I had to come home and we started a long distance thing, but we agreed that, as we were not SERIOUS, we were free to be with anyone during the Summer – although he assured me he wouldn’t do it and I told him I didn’t want to be with anyone either. So, by the end of July, things started cooling off between us, not talking as often, not talking about much stuff and two weeks ago he told me that during the Summer he has realised how GOOD he feels not being in a relationship – he hadn’t been SINGLE(alone) for like 4/5years – and doesn’t want to be with anyone right now. He said that while I was in the city obviously he had feelings for me, but now that we haven’t even seen each other in 2 months he’s not sure that this is what he wants, but it could be due to the fact that he hasn’t been really ALONE in a LONG time… We had always agreed that maybe thing were a bit fast in the sex area, but he told me that he wanted to get to know me more, to really talk to me and be with me and not be with me solely to have “sex”. He told me that he feels this way now but as we become friends, if I still think about him and if there’s opportunity, it may lead somewhere else for us… But even though he said this, he doesn’t want me to be on the hook and we broke things off for good. So now I don’t know what to do.. Because we’ve been talking everyday since the ‘breakup’ but it feels like he’s pulling away even further, altough he told me he wants to talk to me more..? I’m really confused because I want to make myself believe that he doesn’t like me and doesn’t want to be with me, but at the same time I can’t shake this feeling that once I get to the city and we see each other at school and talk to each other he will somehow realise that he likes me and we’ll be back together. Help? What should I do? Do you think there’s something here worth waiting and developing or should I just forget him? If so, how? since I can’t break off contact completely but don’t want to be on the hook…
