What's wrong with him?????!?

Ok so we were talking on myspace and this guy that I really like we were talking and I was in and out of the house tht day. The last thing I wrote to him on myspace was tht black Friday is Hell and I tripped over a shoe. Then he replied LOL dork. Then I wrote haha that's just part of who I am a dork!(: LOL. So then he hasn't replied to me since. And ever since I made my myspace we talked like every day! Almost a third of my myspace comments r from him! We used to go out and stiff and we were talkin once on myspace and he said mb in time or soon we could possibly b togeather again bit just not right now. He was all like feelings can change in time especially 4 some1 they've already been with. And now tht he's gotta new gf. He hasn't been talking to me or hasn't been answering me or anything. And he knows I care about him a lot! And he was all I wish I'd been with Angela crap and stuff mood: pissed and heartbroken and he usually talks 2 me bout it and after tht he puts in a relationship in his dating whatever status....): I felt like I was really close 2 him ...now I feel distant..What do I DO?????Plz help!!! I'm very heartbroken he's acting like this...):
