So sorry you are going through this...I have been experiencing the joy of cult life with my spouse as well, he has shunned me, yelled at me, talked to elders about me, threw away my Captives of a Concept book, etc. I stopped going in June (i was never a jw, was unbaptized publisher, married to a born in who was inactive when we met and married just went back in uber dub mode about 2 years ago) it is ridiculous what this religion does to family and the mind control is mind boggling to me.
Hang in there. Go do fun stuff with your kids, if your wife tries talking about the religion anymore just bow out. Tell her you will no longer be discussing anything related to jws with her anymore. And then dont. If she continues being erratic determine if you can live with that.
