What should I do about this guy I really want?

So I’m having some issues… hah… Valentine’s day of course. =\ So there’s this guy I really like, yea? I’ve liked him ever since I started the current school I’m going too, which has been 4 1/2 monthes. For the first few, he never gave me a chance. I was rejected by him several times, so I completely gave up. My thought was, maybe it’s just not meant to be. A month after I gave up, he came back to me, wanting a date. All this stuff… he told me that he had really just recently ‘noticed’ me. Well, we went out for a month… and he dumped me. =\ He’s said some stuff since then, and I’m not sure if he’s still interested or not. I think he might like another one of my friends, but we seem to have lots of chemistry. His bestfriend told me he talks about me all the time. :P haha Truth is, I’ve never gotten over him… Everything I do makes me think about him, it’s like I can’t even function properly. I really want him back… I miss him so bad… =\ I like him so sooo much. =( I’ve tried to date a few, and pursue a few, but none of them work, and I always get hurt… I always end up going to back to that one guy. I just really want to get back with him… what should I do? Advice please? hah Any advice you have to offer I would really love. Thank you. :)
