This is such a common manipulation tactic by people with personality disorders (and I don’t know the man, so I’m not saying he has one, only that this is common with those who do and he’s employing it so…), my ex is an absolute pro. just completely ignores anything I say that he doesn’t want to deal with, usually things that attempt to hold him accountable for his actions, when those actions are less than “I’m the best everything at everything” worthy. I know it’s infuriating, and I’m sorry it’s happening to you here. :(
