I’m not saying constant active cheating is okay, but rather a one time thing is not worth losing a good relationship over especially if it was just physical. Your ( and most people’s) extreme negative reaction to cheating is not inherent but rather conditioned by the societies they live in and highly influenced by religion. Humans are not monogamous, which is why half of all marriages fail. We’re forcing monogamy even with an abundance of data that it does not work because we’ve been conditioned by society(&religion) to believe it the only real way to love.
However Monogamy works better for women as women in general have a lower sexual drive than men and are less likely to venture outside the marriage for sex. The opposite is true for men as on average they have a higher sexual drive.
There's no such thing as "meant to be" in science. Because that's a normative claim, and science doesn't provide that "ought" leap. Science only gives us what "is," which is descriptive.
We don't need to observe the modern Western habitat to understand things. We can just observe how humans have lived cross-culture since ancient times, and monogamy and polygamy have been the natural social structure of the micro-framework in the vast majority of cultures, and it has worked perfectly because it protects the offspring. There are studies on this.
What you are doing is using the existing modern Western dysfunctional framework and saying, "look, it doesn't work." The reason it doesn't work is that humans socially have been socialized in a dysfunctional way. There's a reason the family unit is more fucked among families in the low socioeconomic ladder. There's a correlation between overall wellbeing and how you've been brought up. This is a descriptive and real science. Everything else is just based on societal biases, packaged with some social science that is not there to explain but to push for certain narratives. And it's the reason many people hold social science in lesser regard, compared to other natural sciences.
Hell yeah, I'm socialized to react to the notion of betrayal, because I'm adhering to good morals and cultural values that has existed for a long time and will continue to exist. You're adhering to whatever is mainstream and eating up whatever the capitalist machine is propagating. A normal person wouldn't lie or cheat because it has negative societal consequences in the macro sense, it literally corrupts everything. But you only see it from a selfish individual level and don't understand you're being played by the forces that only focus on profit and portrays lifestyles that are not good.
It's not that monogamy is not compatible with the human nature, it's that the current socialization in the West and the lifestyles the feminist is pushing for in the name of "freedom," is not compatible with monogamy, which I am to remind you again has worked perfectly since the inception. In social science, we learn about the negative consequences of high divorce rates on the macro level; just look at the black family structure in the USA. It's destroyed, and they have been suffering ever since.
I would also say you lack any personal wisdom because you're saying we react in an extreme way, but don't you understand, that normalizing cheating and calling not a big deal would lead to more cases of such pathology. Why would you excuse bad behavior and blame the person that says it's bad just because it makes your cheating ass life harder. lmao
