When we were dating, my wife and I lived in different cities. I would come up to visit her and stay the night at a male JW friend's house. He was going through a divorce but still living in the same house with his ex. In the morning when I got up, he would leave for work and I would be left in the house with his ex until I left. His ex's super JW sister would chew me out for being alone with her for that brief amount of time.
Recently I made the point to my wife: according to WT rules, if a man stays the night at a woman's house and they are not married, they could be DF'd for the appearance of impropriety. Yet, here my friend and his ex were staying under the same roof, and the elders just took them at their word that nothing sexual was going on between them. (Remember, if they were to have sex, then, according to WT rules, they would be taking each other back). In reality, of course, nothing could ever be proven in either case.
My wife admitted she had never thought about that before, and actually admitted how stupid the whole thing was! I hope these baby steps continue for her.
