Does he like me? PLEASE ANSWER.?

hi, there's a guy in my cl and I think he likes me because when he says a joke he looks over at me to see if I'm smiling, and he does this weird finger thing, it makes clicking noises when he jerks his fingers back and forth and I pretend it annoys me and he does it so I smile because HE KNOWS it pisses me off. x3 so yeaa, he also talks to me sometimes, the other day in gym he was lke "you're all so bad at hockey. O.o" and then he laughed and I laughed and told him to shut up. Idk if he flirts with me or not, but I see him looking at me in cl (I don't know what flirting is.. lol. e.e) Do you think he likes me?
