Re, I’m so sorry this shit happened and is still happening. Is it possible t just stop playing L4D with him or even just stop associating with him all together? You don’t need that negativity and fucking disgusting behavior in your life.
It will probably sound horrible, but I’m used to it. The whole horribleness. I blocked him, so I’m not going to communicate with him anymore, but now it’s just a matter of time until some other comes along. They always do.
