How do I get over a guy that I've BARELY even talked to??????!?!??!?!?!?!?!?!?!?!?!…

There has been a guy that I met at the beginning of the year, and we are literally PERFECT together, like we have so much in common it's insane how alike we are. and we both know it but awkwardly don't say anything. I would literally marry him right now if I could. But there's one difference, he's really outgoing with everyone and such a great guy to talk to, so obviously he's nice and every girl loves talking to him. I'm really quiet and it takes me years to become good friends/relationship with others. He's really nice to everyone he meets, and I know that he'd love me if I were more social, because the things we like are things that no one else understands... like how many girls are obsessed with digital/film visual effects etc.& other geeky technology like that? I've only talked to him about 3 times this whole year, and 2 out of 3 were just about school projects in class. So I don't want to daydream over him like a freak, b/c he'll end up w/ a girlfriend and I'll be jealous of her and depressed. I've never had a crush over someone this bad in my life so if you have any advice I would be greatly appreciated(: and please no obnoxious rude comments. Thank you!
