This article and referenced book seems to assume the betrayed spouse had no reason to suspect an affair and was devastated when he/she found out. Of a handful of couples I know, a few fit that pattern. But in one case, the affair could hardly have been a surprise to the wife because he had done almost everything, including hauling her off to therapy, to try to restore their sex life. Lots of talk, but never resulted in sex. He even suggested an open marriage, which she didn't want. He drew up divorce papers, which she wanted nothing to do with. So thought it may not have been the recommended thing, he told her he'd go out and get a girlfriend. She didn't believe he had the guts. He went out and found a girlfriend, and moved in with her. His wife was shocked that he could pull it off, and begged him to come home. After about a month, he started missing his kids a lot, panicked, broke up with the girlfriend (mistress) and moved back home. Is this book still helpful to a couple like that? The article and book seem to miss the mark on a number of points for this particular couple, as I comment below.
Their minds fill with endless questions about the affair- “How could you do this to me?”
In their case, the wife knew that her husband went outside the marriage to get what she was all too aware of denying her husband in the first place.
“Is she a better lover?”
In their case, since there was no sex at all, the answer would be yes.
“How will I ever be able to trust you again?”
The husband is a very nerdy and otherwise extremely loyal man. Almost impossible imagining him being unfaithful for no good reason. It took years of frustration and trying to talk to his wife before he decided to do anything like this. So, yes, this guy is totally trustworthy if you treat him normally.
My question is, does the approach suggested here and in the book apply to this kind of case too? Is it easier for a marriage to heal when the betrayed spouse realizes they had a role in the affair? It would seem so because it should have been less of a surprise, and the betrayed spouse should feel he/she can be part of the change, in contrast to the betrayed spouse who feels helpless and has to rely solely on the spouse to improve?
