I didn't post his PM because he ignored me. I posted his PM because he acted friendly after I offered to help him, a day later he removes, blocks, and excludes me without explanation (for calling you out BTW), and then insinuates he had to do it because I was harassing him.

I see, so the fact that I posted that message is more of a problem than his duplicity and inability to have a conversation like an adult. Got it. You know what would have prevented that? Him willing to have a conversation about it, instead he chose to hide like a coward rather than explain himself.
