I'm so sorry. I bet you are not alone though. In fact, I have heard of some musicians being real jerks. Tori Amos told this story once. She was backstage at some show, and after the Smiths played, she said to the lead singer "that was really good.". And he said back to her "what the **** do you know?". What a tool.

I hope you don't take this guy's actions too personally. From where I stand, his behavior had zero to do with you.
