The woman is concerned more with making sure that he continues to provide material support and defense for herself and her children. Hence, “emotional infidelity” is more of a threat to women. Polygamy works out okay for both men and women (again, from an evolutionary perspective), so a lot of societies do that for a while. Then we become more enlightened. We start to see the harm in oppressive patriarchy, the injustice of viewing women as property, and we work to correct the situation. But by this time the ideal of female sexual fidelity has become deeply engrained in our cultural morality; sexual jealousy in men has gained a strong memetic, and possibly genetic, foothold. We know the polygamous patriarchy is unfair, but allowing women sexual freedom feels “wrong.” (We’ve also, in our efforts to control female sexuality, repressed and denied it for long enough that it’s easy to believe that women wouldn’t really want, or benefit from, sexual freedom even if we gave it to them....
