I had a boss once who would begin conversations with, “Mary (eyes upward) my, let’s see, fourth, fifth...sixth wife...”
He was impossible to get along with, yet each woman he married was at fault. All of us who knew him thought...well, maybe not.
I had another boss in his late fifties with a lot of framed pictures of beautiful young woman. He saw me looking at them and started from left to right. “That’s Sarah, my second wife, Janice, my third, Karen, (she was a stewardess) my fourth”...all the way to six. All this time I’d assumed they were his daughters. Wife one was not represented because, I’m guessing, she was his age.
Yep, marriage has its problems. But they’re mostly due to the two parties involved.
Those aren’t “marriages” in the true sense. That sounds more like an addiction to the process.
