[URGENT] Does this mean he likes me?

I can relate to the first one cause I do that to my girlfriend. Ive been playfully picking on her since we first met and honestly I don't know why I keep on doing it. I guess its the reaction that she gives me when I do it, if she didn't make it so fun is probably stop but she doesn't lol. I've always treated people like that, in a way I think its kind of like a weird friend test. Bombard them with teasing at the beginning to see if they can put up with it in moderation as time goes by. I guess its kinda like weeding them out from the get go. Yeah its weird. Lol
