How Can I Hint a Guy that I don't Like Him?

[0909]

There's this guy in 2 of my classes. He doesnt talk to anyone and i sometimes feel bad, so i try to talk to him. I dont like him, so i try not to talk to him too much so that he wont think i like him. He's a "jock" and has a girlfriend, so i try to keep my distance. I added him on facebook, two weeks ago and hasnt answered at all (he hasnt denied or accepted) so i have this feeling that he thinks i like him, but i dont, i even purposely waited to friend request him so that he would think that i was desperate and a creep. haha I even stopped talking to him and pretend i dont notice him so that he gets the hint that i dont think anything of him but a friend. I sometimes even feel that hes checking if im looking at him, how do i make sure he knows i dont like him without telling him?
*sorry i meant "WOULDN'T think i was desperate or a creep" it was a typo
