It sounds like, you’re abusive, and blame it on your prior trauma, and when people don’t accept being abused by you, you claim that they’re liars or narcissists.

I’ve had a friend like that. It was hard cutting her off, but in the end our whole social circle agreed that was the right thing to do after enduring so much of her abuse over the years. She was crazy manipulative and always the victim, just like this dude.
