PLEASE HELP..does he like me?

theres a guy i really dont know if he likes me...i used to like him about 6 months ago then stopped and he went out with another girl for two months i am friends with him and not sure if he likes me...when i see him he often calls me dumb and stupid and says i am short but is also nice to me, we talk when we see eachother. a few nights ago i saw him and it was with some people we weren't good friends with but some of our friends were there,when i walked in he smiled and hugged me and we sat down together all night quite close even though he wasnt with the lads and he sometimes looked at his phone and other times at me, he would then tease me or i would talk and he'd tell me to shh, but then we'd talk, our legs were close to eachothers, like on top of eachothers to..i really dont know? he also teases me about previous boys ive been with but we dont really text or facebook or anything..i dunno what to do as we've been friends for almost a year!
