So flipping mad at MIL

Potentially has serious health issues, but because she's a horrible, manipulative, narcissist, she makes my husband out be a bad person who doesn't care about her because he called her out on her bullshit. She thinks because of her age and condition that she can get away with anything and now my poor husband feels like shit because of a fight they had, he told her to leave, and now she doesn't want to talk to him.

Last time they fought like this she didn't talk to him for a year. Of course he will blame himself if anything happens, but that's her whole manipulative plot.

I need to get this man into therapy but he will not listen to me. 😡
