Hello! It's always a bit tough when you like someone, and he likes someone else. But if, as it appears, you're not interested by his looks only, why not be friends? It's always enriching to talk to interesting people and even if you can't get exactly what you want, you'd still have an amazing friend by your side!
Though, if you feel that you'd be too attracted, be careful. Don't get hurt! You'll certainly find another great guy one day. (:
