Why would a guy say he didn’t like me but then randomly message he hopes I am doing well?

We’ve been friends and he moved away, I admitted I liked him but he said he didn’t see anything between us…there were times when he showed signs of liking me too and then out of the blue he sends a message saying he hopes I am doing well?
