What do I do?

I like this guy that says in his gf without a title. We are good friends and we are always having fun. He is moving and idk if it's gonna change everything about me and him. I don't even know if he actually likes me a lot or he was just enjoying my company while he was here :/ what should I do next?? Just let go of my feelings or continue this whole relationship w him??  I don't think I should chase after him even if I like him but I don't know
