I understand he's stunted, a narcissist, not bright.
But how do you deal with someone who responds to facts with things like it's a complete whitewash, dark forces work against him, the press has made his wife's life an absolute misery, they won't leave him alone, she didn't say that the press did, my mother was murdered, he visited QEII to make sure she had the right people around her.
You can't converse with someone like that because they don't possess the ability to reason. What do you do? Walk away, ignore them, call them names, write them out of the will, write articles against them, play mind games.
He's a DARVO. DENIES, ATTACKS, REVERSE VICTIM AND OFFENDER. He denies wrongdoing, attacks the person who tries to make him accountable, and then reverses claims he's actually the real victim and they are the offender.
You don't learn how to do that overnight.
