Does he like me or not? i'm a little confused here?

Yes! He definitely likes you! It's completely obvious. He hugged you from behind and said hey y, stopped at your cl to see you even if he just stopped and looked at you, teases you in a playful way, blew a kiss at you and talks to you alot, so from all that, it seems that he likes you for sure! If you like him back, talk to him about it. If you're shy, wait for him to mention it or make the first move.
