Try actually having open communication. Your as much as fault as that guy.

Your clearly here with a made up mind and no room for discussion or nuance. Thus you don’t deserve anyone’s kindness.

That guy is just here to be an asshole.

You basically have a sign on your head saying “be an asshole to me or don’t talk to me”.

When the only room for discussion is hostile don’t be surprised when you get the assholes talking to you.
