Really want to be with him...?

So theres a guy in my cl. We often make eyes with each other across the room. But otherwise hes very shy and dosent talk much. we say Hi whenever we p each other in the coridoor. He added me on Facebook and he comments on my statuses and we talk for ages. However, we've never actually had a conversation in person... We have lots in common and I really have strong feelings for him. I can talk to anyother person, I just become really shy when it comes to approaching him. What should I do. we finnish college in a few months and I cant bear not to have spoken to him/ asked him out...
