Help with my crush

The boy I have a crush on knows that I like him. My freinds keep asking him if he likes me but he just says maybe or no. I just what to no if he likes me or not but I dont what to be to pushy because I dont what to mess up our freind ship. Even though he knows that I like him he still acts like the same person that I have known sence I was five years old. Even if he dose not like me I still what to be his freind with out it being aqurad.

What should I do?
