It is brilliant. You know someone said it was implausible and of course, when women tell about men doing this to them, it does sound incredibly implausible.
When in fact, it's textbook.
He's made her look like the lunatic, the problem, even to her own family. He's set her up so that she is the unreliable witness.
This is what happens in abusive relationships. I have a friend who lost custody of her son to a violent, abusive man who was utterly charming and plausible to all her friends, family and the court. She'd left for a refuge with nothing but the clothes on her back and her child and even then, the judge didn't believe her because that's how good her xh was. And of course by that time, he had lots of evidence that she was mentally unstable. Because he'd made sure she was.
In some ways I hope they drag this storyline on for years, because that's how it happens in RL.
But if they do I might have to give up listening because it's so draining.
