I fail to understand why you continue to be this woman's savior.
I wonder if you are not enabling her behavior by refusing to cut her off and leave her at the mercy of her actions.
Take note that I would not normally say this to someone who's spouse had begun to wander in some way. But your wife has not BEGUN to wander. She is a chronic adultress with major, MAJOR psychological issues that she refuses to address.
By being her protector, you allow her to never fully address her problems.
Personally, I think I would have been inclined to communicate to her that I had no interest in her ongoing man problems. After her many indiscretions, the only way she could merit my concern would be to remove contact with any new men in her future. At some a show of good faith on her part is LONG PAST DUE.
You continue to allow her to play her game, and you continue to choose to play a part in her escapades. This is ultimately unhealthy for both of you.
Blessings,
Bill
