Should I Even Try Anymore?

My boyfriend (well I guess ex) moved to the other side of the world last month until January. Before he left we hung out every single day, but never made it official.

I knew he liked me and I liked him but I guess I was just thinking, why want a girlfriend when you're in Thailand?

Anyways we kept talking and then he flat out stopped talking to me, for a whole month because he apparently heard I was "sleeping around" (I had sex once at a party when I was drinking..totally regret that.)

I asked him and we got in a huge fight and then decided it was easier if we were just dating, so we were dating. Then, 2 days later he sends me a facebook message saying "I still feel ****** up about this, I don't think its going to work".

Is there anything I can do, or should I just leave this? I love him so much, I'd do anything, but I don't think he would want that. Please help me!
