The underlying cause of divorce due to infidelity in the U.S. is approximately 90%. The divorce rate is approximately 50%. Assuming that only a third of infidelity is actually discovered, that would mean virtually every marriage has had at least one partner cheat over its duration. 70% of all divorces are instigated by women. If they have a college degree, then the number is 90%. It’s the inverse for men because only the top 10% of men have the opportunity to cheat, which means that virtual all men who can cheat, do cheat, but the vast majority of men do not, which means it’s primarily their wives who are doing the cheating.

10% of the time, a married woman cheats during “girls night out.” Only the top 10% of women get approached to cheat; that means virtually every attractive woman has cheated after a dozen girls nights. Any woman will cheat given the right time, place & opportunity. Since every attractive woman is approached when the time & place are right, meaning they are without their husband at a place with men, even a woman who would never imagine she would cheat, even with 1000 to 1 odds, will cheat over the course of 1000 approaches. There is no such thing as a woman having a platonic hetero male friend: if she offered him sex, he would enthusiastically take it. It’s remarkable that anybody remains married?
