Ok......If a HUGE flirt does this to me, does he like me?

Ok, this guy I liked for 3 years strait, is a huge flirt. But there are some things he does with me that he NEVER does with other girls. Well, we fight ALOT like we call each other gay and stupid. But the next minute we are joking around and stuff. He also told me just to be myself, and I look fine (over and over). and when I said thank you, you look good to. He backed away really fast and said "ewww" but he was just kidding. and also he slapped me (not hard) once on my face. and he also punched my arm (once again not hard). And lately he has been walking by our lunch table licking his fingers and doing drops and stuff. And in cl he walks by my desk, the long way for him, (but his best friend sits in frount of me so idk) He never does ANY of this with other girls. Does he like me? BTW I am in middle school 7th grade
