I think the fact that many spouses who want to leave a R, but decide not to is more the norm than you might think.
Heck I think ALL of us at one time or another had at least passing fantasies of leaving our spouses for another person. Or dreaming about having sex with someone else. I mean let's be honest. It's human nature.
Whether they act on it or not is another story.
But in terms of people thinking about leaving their spouse, but not doing so for one reason or another, is extremely common. So I'll give humanity the benefit of the doubt.
Stuck,
I'm not following you. My point was that someone caught up in an EA or a PA (or very close to it), who decides to get the counsel of their pastor and also an IC, and is still operating from a strong moral base, is VERY unusual.
People thinking about leaving, but they don't . . . not so uncommon, as you say.
