A question for honest people?

Does he like me? I've liked him for 3 years (I'm lucky because he's been in all my cles for 3 years) and Im 12, so is he. In the begining of the year he would just talk to me, show off and basically flirt. But he would do that with other girls. But then we started fighting back and fourth. And after that he started teasing me by calling me bec-bec and he would get in my face and start doing clucking noises and whenever I turned around he would do that! But after I told one of his friends I thought that was annoying he stopped almost immediatly. He never did that with any other girls. And now he has been smiling alot whenever we talk and I've caught him staring. And I've also over-heard him talkin about me.But the thing is he's really popular and I'm not. And he has this friend that tries to act just like him. It's very annoying, but they're really good friends. And she hates me, and she makes this very clear to me and prolly my crush. Why would she act like this? Does he like me??
