How do I know if my crush likes me Gay?

Well, the person i have a crush on i think he likes me, or used to like me b4 he started dating Taylor, anyway, he would just tilt his head, stare at me, and whisper to himself, "wow". i think he use to like me. and another tip. just tell him/her that you like them. trust me it feels sooooo good once u finally get it out. seriously just trust me i promise you'll feel a lot better.
