Why won't this guy take the hint?

[Selena Fan]

So this guy friend of mine (who I don't consider a friend anymore) asked me out 2 years ago. I rejected him and he still can't seem to move on. I've ignored him, deleted him off my Facebook, and try my best to stay away from him. We have a class together and he's always staring at me and trying to get near me. Sometimes he'll try and be loud to get my attention. I just ignore him. He's driving me crazy because I can't even have a conversation with a friend without him trying to listen in on what I'm saying or doing. Is there anything I can do that will make him take the hint that I'm NOT interested in him?
