I very much thank you all for taking the time to respond. Here's some additional information.
The wife apparently got a scriptural divorce. At least they are not living together anymore, and he moved to a different congregation.
The other woman was in the same congregation.
I know for a fact that the man was in contact with at least one ministerial servant. Does this mean he was not disfellowshipped, only asked to change congregation?
The daughter of this couple did meet with the man recently.
I believe both of the people involved in the couple had a very good standing in the congregation. Knowing the person, I doubt she would have spread any gossip. But I am sure people in the congregation knew about the cheating. You know how the wife is always the last person to know.
She's moving to another congregation, too.
I ask the question because I want to know the person's possible standing in the congregation. I know this is a lot of speculation.
I recently checked the Panorama series and found that a wife who accused her elder husband of molesting their daughters was told to be a "good wife", shut up, and pray. In the end, even though the man had indeed abused the daugthers, AND THE ELDERS KNEW, the congregation stood before the man. The woman and the girls had to leave the home, and "lost everything in one day". It got me thinking.
Thank you very much, once again.
