How do I know if he likes me too?

just go up to him and start a conversation, find out what he likes and see if you have anything in common. dont tell him you like him right now, I did it and it is working out good for me, but people are different. talk about what he likes, then you are going to know when to tell him you like him, you will feel it inside you, I promise that. I hope everything works out for the best.
