Back on the general topic, I think that a greater awareness and appreciation of human rights, or equality etc has made so many men appear to be poor partners now.
My grandparents were married for 60 yrs u til my grandfather's death.
My grandmother is an intelligent woman who had no opportunities really.
My late Dad described her as "the brains of the operation" in ref to their relationship/household.
My grandfather regularly called her a stupid woman, in company, and ordered her around and was chauvanist etc.
He tried to kiss young female relatives on the lips when greeting/taking leave.
She showed me letters from their early dating days which suggested he was playing the field or trying to.
She actually started dating him by staying with him when her friend, who was supposed to be meeting him for a date, took exception to his behaviour, and left. She stayed.
Those are all things that women now - entirely rightly - would be taught to be red flags/unacceptable. And would've led to the relationship not starting or not progressing to marriage and kids or breaking down if it had. Not a 60 yr marriage.
And sadly don't think the world is any less full of entitled, sleazy, chauvanist, verbally abusive, arrogant etc. men.
Their behaviour is possibly even worse than before due to porn and very available/accessible prostitution (a few seconds on your mobile) and a backlash against whatever equality/rights women have got in recent decades.
