What should I do with this guy?

there's this guy I've been talking to for months now, and we have so much in common. we're both into music and we have the same kind of job, so we have a lot to talk about. we're even in the same kind of courses at school! we talk on facebook a lot and the other day he was flirting with me and complimenting me. we've also talked on email, skype and phone. do you think he sounds interested and wants to ask me out? he asked me how other parts of my life were going besides work and music, so I think he was trying to find out if I'm single (which I am). What do you think, is he thinking of asking me out? I've had a crush on him for years, and he's flirted with me in the past too. The only problem is he lives in America and I live in Canada, but it only takes a couple hours by plane to get there. He even invited me to visit him too! What should I do about him?
