I told him I liked him and he never responded, how do I get over him?

Okay do I took the chickens route and sent him a message on facebook (yes, I know chicken, bad idea) saying I like you and I want to get to know you better and then he never messaged me back (that's fine, I kind of wanted him to talk to me in person now that he knew there was not much left to say awkwardly.)Then the next day at school ne never talked to me about it either. I figured I would wait a little and give him some time to figure out what he thought of everything, however then the next three days he was sick, we had a test on the day he came back and today I did the silly desperate thing of putting my stuff away slowly in the hopes that he would talk to me since we were alone and no one else was in the room (except for teachers but they were already on their way out the door so no excuse there either) and he didn't. I feel like such a loser. I actually feel especially embarred because girls always talking about the crushes hey have on him and how attractive he is, and that is how it started until I realized that I do like him as a person! That just makes it hurt more because I did expect him to have the decency to tell me he isn't into me. It just burns right now especially since every time I am around he gets this hurt look in his eyes and I don't know why. I decided to tell him how I felt because I was fairly confident he liked me back (he looked at me a lot in cl, he would find little reasons to talk to me, sometimes when he found those reasons he would get a little shy which is not normal for him however he started talking to me normally eventually. There were some other little things as well that I don't need to go into.) I just feel really embared and don't know how to get the heck over this guy! It is driving me insane!
