If your Christian, you also have a duty (after private confrontation and she refuses to end it) to disclose your wife's sin to the Church/Pastor who should bring it to the attention of the Church elders and any bible study group the wayward participates in. I also think, in short order, the children of the marriage must be told lest the little narcissists conclude it's all about them and something they are causing. The children need to know the truth about their lives too...in an age appropriate manner.
My WW planned way ahead on this one.
First, her OM is divorced and I doubt his X would care at all.
Second, the W suddenly stopped going to Church oddly right around the time I believe the EA began. While I was not a regular attendee (I sure am now), she blamed the fact that the Church ousted the pastor because he was having an affair. While my IL's felt he should have been forgiven, I could sort of understand the Elders' decision. After all, this is their decision to make.
In hindsight it's pretty interesting that this was the reason, and one that the W objected to. The timing couldn't have been better for her.
With her turning her back on God and our Church, I'm guessing she no longer felt there was a moral authority dictating to her. What completely floors me is that she was and has been a devout Christian for many, many years. Extremely active in the Church and even sang in the choir. I'm the sinner in need of saving.
This is where I have a hard time as well. I haven't told anybody at the Church - not that it would make a difference now as she's buffered herself from it. But I suppose I should, at least they can pray for her.
