Why didn't he want to say goodbye?

We never had a relationship, but we - and everyone else - knew that there was something going on between us. We both had feelings at some point, I know for a fact that I had feelings until the very end - I had to move away from the city.

When I tried to say goodbye, I REALLY tried - texted him to meet, etc - but he put some excuse and avoided saying goodbye.

Why? There was never an argument and we were theoretically friends. I'm hurt and I don't understand.
