I really like a guy at school........?

Question

I have liked him for a while now and he kinda knows. (dont ask another story). Anyway we talk some and have a lot in common. I really enjoy talking to him. In the hallway I see him looking at me and when I look he smiles a little. He says I look like my sister.
He has a younger and mean girlfreind who is mean to everyone but not around him. He knows though. At the dance he didnt hang out with her and hung out with me a little bit. Do you think he likes me? what should I do? And I definitely dont want to be the reason for them to break up, if they do.

Answer 1

he must like u
