Overly friendly or does he like me?

Theres this boy at school who I used to like, and from that we became really close friends. But recently he's started to pay more attention to me, and I've noticed he's flirty towards me. He always compliments me, and sometimes he says "haha joking" and then does this flirty smile. For example the other day he said "theres only one girl in the school that I would go out with, and that's you" then he said the joking thing, with the smile. Another thing I have noticed is that he likes to touch my hair, and hands etc. I'm really confused, and I don't know if this means he likes me?
