I have had the opportunity to research and write concerning this subject (albeit some years ago). As surprising as it may seem, according to a number of surveys the percentage of men who remain faithful to their wives throughout their marriage is consistently in the 70-80% range. True, some of these same men get divorced and marry someone else, which others call serial adultery...
I know the stats you’re referring to. So 20-30% ADMIT they have cheated. What percentage have cheated but don’t admit to it?
Ask any woman if she has had an abortion. Almost every single woman will say no.
Yet abortions are happening every day.
If 20-30% admit to being unfaithful, I would bet money it’s 50% who are actually unfaithful. My best friend’s DAD told me he had cheated on my friend’s mother. I asked my friend, “Do you think your Dad has ever cheated on your Mom?” He emphatically said “No way.” But I knew different, from the Dad’s own mouth. (Of course there was no way I was going to hurt my friend by telling him about his Dad’s affair. I learned long ago — confessions only make the sinner feel better. Confessions hurt the one who is hearing the confession. If you cheat, you damn well better keep it to yourself, and live with your own guilt, rather than putting it on your spouse out of some twisted need to “tell the truth.”)
