Is there anything I can do to fix this?

So I'm pretty sure a guy friend of mine picked up on the fact that I like him. I tried to hide it, but he figured it out (even though I never explicitly told him I liked him, I think he noticed the small things I wasn't able to hide very well). Now he's acting weird and ignoring me to try and get me to stop liking him. We were friends before this, but now I don't think things will ever be the same. Is there anything I can do to fix this?
