what should i do about this situation with my crush?

I need really good advice. A whole semester I have liked this guy. And he knew. And people asked him a million time do you like (me) and he would say no, or only as a friend but she's pretty. Just the other day my guy friend asked him do you like (me) and he said yeah? Why have he been lying this whole time.. I don't understand. Also today my friend talked to him and he's mad at me I guess. Cause I "play with his emotions" even tho its the other way around.. He said he's done and why like someone who acts like they don't like you back. He was so mad. Me and him been ignoring each other for about a month. Should I talk to him tomorrow. And just talk about this. I really like this guy. I never felt this way about a guy before. I'm so lost..
