The facts are not with you on this one as to divorce. The lower social strata gets divorced much more often, by a lot. Prenups have had an impact on that.
Try not to take this to relationships. This is getting the woman’s attention and keeping it for a while, not marriage etc..... There are hundreds of other things that men need to do to keep a woman.....
It is like the joke from Dr. Laura (sort of): “Proper Care and Feeding of Husbands” is a 100 page book give or take. “Proper Care and Feeding of Wives” would take a section of the library of congress.
