Does he like me?? really need help on this!!! :(?

okay this guy, i wont say he's my close fren but i am his closest female fren in our large clique of frens. i dont know if he likes me or not because he gives me mix signals i'll say. whenever we go out for lunch or dinner, he'll always invite himself to sit right beside me. at times, we'll just share food together. he likes to make fun of me in front of every one else. when people teased that we're tgt (though not), he'll go with the crowd and give me a hug and played along that we are. in big groups, he'll just keep on talking to me and teasing me. because he likes to sit beside me, his legs and mine will always touch and we'll sit shoulder to shoulder. he'll hug me and i feel the warmth but sometimes i wonder if that's a frenly gesture or that he likes me. we always bickered with one another regarding small stuffs. but he never calls me everyday or message me everyday. but he always teases me that im fat and called me bro but he never did that to any other girls. im currently confused coz i like him too.
