Herb, I've been in your wife's shoes for something like 6-7 years as far as the feelings about my H looking at other women, cheating (I consider it emotional abuse, but it was never verbal or physical).
I don't know how I would feel after 20 years. It sounds like you need a mediator of some sort to step in and diffuse the situation.
