Help PLZZZZZZZ?

i have known this guy for about 6 months now and we become really good friends.he tells me im one of his best friends and he feels close to me. we have a weird relationship,like we are always teasing one another,i say mean things to him and he says mean things to me, we bicker all the time but at the same time we will stick up 4 each other. he is always punching me and touching me or plays with my hair..he doesnt like it when i ignore him,he gets all hot and bothered about it. sometimes he gives me these looks and i dont know what it means. is there any chance he likes me more than a friend?? do i like him? coz i don mind him hugging and touching me all the time..
