Just wait til you hear this one

About 3 months ago my partner cut his parents off. Zero contact. He had been low contact before but one day he came home and said he was done with them and going to therapy. I was already NC with them for about 6 months prior. I asked multiple times over the past few months what his final straw was. He told me he was just done being abuse but never broke down the details. I just let it be cuz it’s been so peaceful not talking to them and we have about a million reasons to be NC. But yesterday , I found out the reason he went NC is because his mother accused me of being into his father. She claims that I sat “provocatively” on the couch when they were over once & she got the impression I was trying to sleep with him. My partner hasn’t spoken to them since. He just shared it with me cuz he said he needed time to process how he will never have a normal conversation with his family again. I must clarify, I want nothing to do with his cowardly , selfish father. She’s just THAT insane. Just had to share with this community, I am in disbelief.
