Advice ?

ok so, there was this one guy that I've had a crush on for a while.. And, yes we dated for maybe 2 months. And he broke up with me because he really wasn't feeling it.. so, I had to move on of course.. And when I did, he came back saying that he likes me again and that he messed up and I believe him, and then maybe after 2 weeks he just said he wasn't feeling it. And he does this every time I try to move on.. What's going on? It's like he doesn't like me but he likes me enough where he won't let me move on.. ?
