Does he like me? He knows I like him and despite me saying let me know if you don't he has never said he doesn't like me but never said he does either. He acts different around me than other girls too

To be honest, there's not going to be a way of knowing for sure unless one of you makes the first move.

What is it he does that makes you think he likes you? You mentioned that he acts differently around you... This can be a pretty big sign that he has feelings for you - but exactly how strong and what he intends to do about them kinda depends...

My advice would be to act friendly towards him, make it clear you're interested, but hold back from outright confirming it.

If he responds well to this approach, maybe organize some alone time together - go watch a movie or go for food. Something casual that could be perceived as just "hanging out", but will allow you to suss him out too!

First never ever put anyone on the spot and expect a truthful or even an answer because it wont happen. You need to know the answer you seek is in his actions more than his words and actions do really speak a whole lot louder than words ever can. So watch his actions around you and especially if his friends are around and that should tell you. Also trust your gut feeling as the heart has been known to, and does lie.  Good luck
