Does he like me?Or am i just thinking so?

Ok there is the boy in my school and he always looks at me during class and when ever we have to do group work and always calls me as his partner be for i even get a chance to speak and like at a track meet me and him hung out a bit and he took me neck less and me hat and started to run away. i chased him and got it back and the he said that we so go take a walk through the high school so we did. and then we were walking through the high school and he saw this semi dark hallway and he said we should walk down it so he like pushed me down the first park of it and the he kind of looked down at his shoes i asked him what was wrong and he didn't say any thing then he started to walk a bit slower and all of a sudden he wrapped his arms around my waist and stopped me he pinned me up against the wall and then the janitor walked by and then we both cracked up laughing. the next day at school he wouldn't even talk to me he looked at me every once in a while but wouldn't say any thing to me. he didn't even pick me as his partner in class.
