What Do I Do If My Crush Likes Someone Else?
Do your best to impress him but don't be a bitch to the other girl he likes be nice to him.Maybe sit down and talk to them both separately and let them know how you feel.If he doesn't like you back then be nice and accept the fact that he doesn't want to be with you.I'm sure you willl find another boy.
