I wrote based on my experience. Unfortunately, you misunderstood my point in the examples I gave. The truth is most times, women do abandon their sexual responsibilities, especially after childbirth. I know because childbirth changes women's sexual urge, unlike men.
My references are the major reasons men seek external affairs. And no, I don't make excuses for these men. I'm simply highlighting how the wives, too, should take responsibility for their part in the betrayal, instead of taking out their frustration on the women their husband date.
