I was on a committee where the wife came forward and admitted adultery and told us she needed to be disfellowshipped! It was surreal - we were saying no, no, think about your relationship with Jehovah (I know, I know ...) but she insisted she was not repentant as she couldn't stand being with her insensitive bullying husband. I even suggested I had never heard of her having a "male friend" - or her adult children who were witnesses had never seen one with her either. But she insisted it was true.
So we DF'd her and he got his "scriptural" divorce.
I always liked her (no, not in that way) and volunteered to do those occasional follow up visits every year or so and about three years later (ex hubby had remarried) I visited her with another brother and asked her about whether she wanted to "work towards reinstatement".
She said "Freddo, I don't suppose it matters now that (her ex) has remarried but I never committed adultery, I just wanted to be free of him and to be honest I'm glad I'm not a Witness anymore!"
