Does he like me? Do i like him?

My best guy friend use to never care about me my feelings or opinions... but right now he is kinda getting all... boyfriendy... like when we are watching a scary movie. He would sit right next to me, like our sides are smudged... He yelled at a random guy on FB (idk who he is) that randomly asked me out. He hugs me really tight at random times... And he will rub my hand or my shoulder at school, in front of EVERYONE! He even grabbed my hand... and pulled me across the court yard during lunch... he didn't care that everyone was looking at us.... even his ex! And he will just... care... like ask me what wrong and talk about my problems... Its weird O.o So, now i think i like him... but i don't want to... but when i see him i have to smile...
