How do I get over a jerk?

I'm a sophomore. And there's this guy, he's always been a jerk to me exspecially in junior high! I'm not gonna say the things he did to me, but they hurt me a lot! He's matured of course, but he is still arrogant. Every once in a while he has his moments, but he can still be a jerk. For some reason I like him, but I really don't want to! hellppp!!!
