What should i do?

Well, truthfully I don't think you 'love' him, it's a much bigger word than some people take it for these days (if you know what I'm trying to say by that). But ifyou do infact like him, you could always do the good old 'grape vine' method. Get your friends to find out, or your friends to talk to his friends... Or you could ask him straight up...
If you just want to tell him that you like him, then I'd suggest the grape vine method, because I have found that when someone finds out you like them - they start liking you a little bit... But anyway, I hope that makes sense to you. If not just leave a little block down there and i'll try to say that again lol in a more organized fashion. Good luck with everything.
