Does he like me? I need your opinion...

Hi guys!
So there’s this guy…. and I was wondering if he likes me. First of all, he always has an excuse to touch me, for example, when I was leaning against a wall, he gently pushed me (to go away).... Dunno what that means. Then, he always is mean to me in front of his friends, but teases me when we’re alone. So once, my friend was there with me, and he poked her with a straw hard. She said it hurt, but I guess he did it to me gently. Also, I never have seen him fix his hair, except when I’m around. It’s weird! I really appreciate your guys’s help, and thank you! Please write your answers detailed!
