My MIL revealed to me today some details of their conversation last Thursday. My MIL told her how the OM is not good for her, and that she shouldn't continue in the affair, etc, etc.
As my MIL explained to me, my wife's response was not defensive at all. She said that she had a very "defeated" attitude. She kept nodding her head and saying "I know, I know".
