Help with a girl QUICK ANSWER PLEASE?

Doesn't seem like a friend to me. You should tell him what he's doing is not cool.
If you want to tell her, say something like "The other day I told __ that I liked you, then two seconds later he's all over you. Idk if you like him but he's probably only doing it to get me mad. He might not actually like you."
Or you can tell him that you like some other girl, and maybe he'll go after her instead?
