Does he likes me if he looking at me or is he just curious?

Well, I think he might like you. BUT don't get into something you know isn't right just because he does. Sometimes, it's best for a girl to make the first move. Just walk up to him, say hey and start a conversation. Talk about anything. Football, music, movies! Anything! Some guys like a girl who start the conversation FIRST. I think you should try it :) If it doesn't work, wait a little, and wait for him to come to you :D
