Do you think he likes me? I'm serious?

SO there's this kid, and i have all my cles with him. He's my best guy-friend. we go to each other's houses, we ride our bikes places by ourselves, we talk a lot. and Yesterday, we were talking outside of school, and when his ride was leaving, i had just finished some story, he patted me on the head, and kept it there for a minute and said, sorry Rach, i gotta go, i'll see ya tomorrow. and we fool around together, like we'll be poking eachother with pencils in the middle of cl, or jumping on each other, you know, horsing around. But i'm not sure if i like him, i'm kinda confused, but i think i do.please, any tips to catch his eye? he loves basket ball, he's a real athlete, and we're already really good friends, but i don't want to but our friendship in jeopardy
