When someone is in a cult and brainwashed it is hard to reason with them. My whole family is in and I deal with this almost daily when I speak to my 80-YO Mother. She is the picture of Stepford JW woman. She recites the bible verses, the mags, the books, and other propaganda; I know the stuff by heart.
She also drove off my father because she was looking for a better model to take into Paradise after Armageddon (1975). Unfortunately, for her, the Big A never occurred and she was left alone. She has countless female friends just like her. There is something in that KH water...
If you want to stay married use the "Subjection" card. Even my Mom was biting her tongue when Dad told her to do something and he said "I'm the man and in charge, the Bible says so..."
If you don't, well, you have so many avenues to have her kick you to the curb as an Apostate.
The tough part is a JW will bring up "This System" and how bad the world is to try to suck you back in. I just grunt and say I have to use the bathroom and get off the phone.
Good luck.
