Does he hide his feelings? (does he like me)

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.

To: STEPH247: Did you post to the right thread? To: ANONTYGIRL: You say "lately" he's been smiling at you, maybe his sign that he may like you. His friends teasing him in front of you is a small assurance he may like you. How are you helping him? So go for it...
