Does he like me?? I have another guy now :D

Ok this guy in my gym class is always smiling when he sees me. Sense i sit out in gym, when we're playing dodge ball, he sits right next to me....pretty close too!! He tried to give me a high-five on our way to lunch. I asked him out but he said "uhhh....oh i gotta get this ball!!" and then runs away. He always says hi to me when he sees me weither hes with his friends or hes by him self.He just extremely nice to all the time.
