Up until relatively recently, the number one cause of death in women was childbirth, with many of those babies not surviving either. That fact alone probably goes a long way toward explaining how we’re wired.
While your point is true, I really don’t think you need to go that far. All creatures are wired to reproduce, its a fundamental biological urge, and while humans are fortunate enough to have self awareness and intelligence, that make us aware of these things for what they are, it does not free us from them.
We need to pass along our genetic makeup, its a drive for most that is as fundamental as breathing and eating. As such at a primal level we are all going to try to do what we can to do so. For women its a much heavier investment, at least at the base level. She needs to make sure her and her offspring are going to be taken care of, so desires are going to be to mate with people who fit that mold... at a base level for a guy, literally any port will do, with the desire to be the most attractive partners he can find.
These drives on both sides explain a lot of behaviors, and yes, folks women cheat to... Single women can cheat for reasons like trying to trade up... or have found a guy who is a safe provider but doesn’t do it for her sexually... Of just because she really isn’t in a place where she should be settling down... etc etc... Married women cheat too, history is filled with cuckolded fathers unknowingly raising the children of other men. Traditionally though women have more to lose from cheating, so while they certainly do it, even then the approach to sex is still not on par with a male.
But men produce sperm daily, women are born with the number of eggs they will ever have. Its not surprising sex is approached differently by the genders, but what is just irresponsible today is how poorly women are raised to understand the male today... Women/girls are not being taught the wisdom of their mothers when it comes to men. Men are pretty simple and base creatures, they are not really that hard to figure out, but girls are being fed a bunch of feminist nonsense instead of simple realities known by women for eons. And that just exacerbates things.
You want to drive your boyfriend or husband to cheat? Tear him down, particularly in public.... nothing will move him away from you faster. Give him support, even if you are faking it at times, and you will be amazed generally how loyal and hard he will work for you..... yet somehow this simple reality is just lost on many women who just can’t grasp, stroking a guys ego in little ways, rather than asserting some feminist dogma is far more likely to get you what you desire and produce a happy outcome for all etc...
