how do I get a guy to stop liking me?

[christi]

ok so there's this guy in my class who makes it obundently clear that he likes me and word has it he's gonna ask me out. I DO NOT like him, but I really don't want to hurt him. his friends follow me on twitter so I've been trying to make alot of tweets about the boy I do like, so his friends see that I like someone else. I don't know what to do. maybe I should just confess my love for the guy I like and perhaps we will get married before the other guy asks me out. jk. but seriously my stomach hurts thinking about having to reject him. I feel really bad about it. help me!!
