The reason for so many divorces nowadays is often (not always) simply women not wanting to be wives. It basically started with my own generation and I've seen it first hand. Marriages which fell apart before were either caused by the husband being downright abusive/substance abusing to a criminal degree or the husband falling for his secretary; sometimes by female adultery as well.
If a couple had problems otherwise, it was suggested they stay together for the sake of the children as society disapproved of divorce. Divorced women also had a certain reputation. It was practically impossible for a divorced woman to remarry someone decent. For instance, in one case I know the woman had to settle for a fellow divorced man who was much older and not a great breadwinner.
Women were supposed to stick with their men through thick and thin. In one of Miss Silver's novels a woman's boyfriend disappears for several years, then returns the night before her wedding and tells her it will happen again in the future, and since he knows she loves him, she'll just have to accept it. She does and cancels her marriage. (Of course, in reality the guy is some sort of a secret agent, but she only suspects it).
Good women were expected to love sacrificially, unlike harlots and gold-diggers. This all changed somewhere in the 1990s (I think earlier in the USA but Europe has been late with these trends). While I don't like giving examples of real people on this blog, I will say that I see it all around me in the real life.
Some of my (female) acquaintances just decided to opt out when they encountered some real problems. As someone put it, "why should she conform to a man?" Others complain that they work too much but would never dream of even cutting their work hours though the husband makes a decent money as they value their independence. Yet someone else never bothered with even the minimum of housekeeping (there are servants for that) or would cooperate with the husband's spending plans which led to predictable results.
Here I'm talking about my peers, women with university level education, who were capable of earning a decent income which wasn't always the case back then. Hence the push for all women to keep on working while married and going for high-paying college degrees, which leads to even more divorces in younger generations, and among lower classes, men with chronic pain in their backs.
Those who stuck with their husbands through thick and thin and adjusted themselves to their needs, sacrificing their careers for the sake of the family are still married and sometimes doing very well financially while their divorced friends chide them for being oppressed. Well, may be they are, but at least, they are still married and doing fine.
Marriage was absolutely destroyed by feminism and it was done on purpose.
