What should I do about this guy that I like..?

OKAY, this is a really weird story, and it's never happened to me before so i have no clue what to do about it. I'm 16 and like i moved to a new school this year for grade 10 but the summer before i moved to the school i met a lot of people that already been going there and they're really good friends with me now, and this guy was included. In the first few months of school we were real tight buddies and we would bicker like sister and brother and laugh about it together but he started getting quiet and then one night on msn one of my friends told me he liked me and he was in the msn convo too and he was saying she's lieing and saying noooooooo and stuff. The next night on msn, he told me it was true but i never liked him that way or even THOUGHT about it! So he stopped talking to me in real life and he told me on msn he was avoiding me and started talking to me on msn only. He completely ignored my existence, and still does. But anyway, i started liking him a few months later because i realized how sweet he really is and is different from other guys i've liked and i told him i kindof liked him and he was pretty happy about it, but now it's been like 4 months and i haven't talked to him on msn at all he hasn't been on and nothing is happening in real life of course. I have feelings for him that i can't explain, and he's really loud and funny in real life but he doesn't talk to me. i catch him lookin sometimes, but it's never a smile its more of a blank stare which confuses me. Does he hate me? Does he still like me? What should i do? I thought i should talk to him in real life, but i tried that once and he just ran away from me. My friend also once dropped my pencil case under his desk and when he came he just looked at it like wtf and pushed it over to me without even looking at me as if he didn't care. I understand he's shy about liking me, but what should i do and by the way, im kinda afraid of rejection and if he rejects me i'll only be hurting myself and i know no man is worth my tears other than the only one who can make me smile BUT SERIOUSLY it's confusing :(
