Suffering from embarrment???!?

Okay, I'm going to make this concise as possible. I'm embarred a great deal and I want to know how to escape this humiliation. I liked this guy,so I talked to him via fbk a couple of times; then he no loger responded. Even though he stopped I kept sending msgs a few times, but now I stopped. I see him at school, but not often. I waved once, but never actually spoke in person. Well, I'm embarrased to even be near him because of my irrational action, so I try my best to avoid him during school hours. He made it clear he doesn't want conversation by not responding, I wish I hadn't sent those extra msgs; but it's done now. I just wish he would have told me he didn't want to tlk cuz I take things personally; it's funny he nva removed me as a friend, he even liked my status. Anyways, I'm one of the most respected and reserved girls known, he's a playa (just found out). Idk, I only want to rid myself of the feelings of shame I have. Btw, I'm done chasing him.
