There are gazillions of factors that lead to divorce. I divorced my ex after 22 years due to his character issues and other infidelities which were part of his extreme narcissism and sense of male entitlement. In my generation ( I am 54 ) there was still a huge amount of sexism. Men wanted you to bring home the bacon and still cater to them in every way, per the fucked role modeling of the 1950’s nuclear family scene.
I was “expected” to make money, raise our daughter, take care of the home and be a porn star in between. My ex had the mindset, expressed between lip service to the contrary, that he was still “superior” to me because he earned the money, or later, more money than I did and that the “man” was the tribal chief to be deferred to.
Sure, I take responsibility for certain things, but his issues were the deal breakers not mine. Mental and emotional issues and fucked up programming are not gender specific and while two people can and do, often grow apart, as the relationship progresses, much of the time peoples personal problems are where the fault lies. Women are certainly catching up in the infidelity arena but, historically more males than females take the cheaters path and subscribe to a sense of male “entitlement.”
Stereotypes do contain more than a grain of “truth” in a lot of situations.
Younger men are often less mature than women, have a harder time relating on an emotional level and often neglect their relationships for the pursuit of career.
