First off, I feel like less of a man just having read this. Secondly, that was the equivalent of a slap fight between two little kids. He obviously got under your skin big time. I get it, it happens, that's why I stay my ass out of pvp. But to pester him with messages got borderline weird. Best way to deal with that is take a deep breath, utter a few choice profanities and go about your business. As soon as you message some random for something they did, they win.
