Does he hide his feelings

I was friends with this guy for 3 years now and I don't know if he likes me, lately he has been smiling at me and feeling 'guilty' if I help him. His friends tease him when I'm around him and I just want to know if I should make a move for it. I like him, a lot, I just need assurance if he likes me.

He likes you, 90 percent of male/female friendships one party wants to bang the other. Hes scared to make move

Thxs for your help! :D
