How can I possibly get over him without any regrets?

So there's this guy. Compared to my past crushes, he's the most intense. Yes, he's good-looking but he's also nice and funny. I'm Asian and he's mixed w/ black and some other race. So here's the dilemma, almost every girl likes him, too, including my best friend, who's white. ha. At school, due to cles and stuff, my best friend gets to hang out with him all the time while I don't. They were also voted in the yearbook as having the most captivating eyes, and yes I admit she is really pretty. I"m jealous and I don't want to be. I would have gotten over him a long time ago if I had known there was no chance with me but every time I see him, we would lock eyes, smile, and say hi. But that's basically it. I don't know if it's my desire to want him to like me but I always feel or think that maybe, possibly he likes me back. But I always feel that it's stupid and why would he ever like me? So yeah, I really wanna get over him cause it hurts ALOT but I don't want to have any regrets. Help.
