People used to just not divorce, even if they split up.
It's still that way in many countries. One of them just moves back in with relatives or gets an apartment, and it's like, "Well, that didn't work out."

And be there for the kids when need be, and not remarry again
Yeah, there seems to be a sort of panicked run for the courthouse, sometimes, that isn't warranted. Perhaps to get financial/insurance stuff sorted out?
But commitment is commitment. Divorce rates way to high. I think it's the primary reason for our generation of teens on autopilot that can't do basic algebra and have even more kids out wedlock.
Idiocracy here we come.
Significantly more women have been married than men. 😬
Four men have no wife, one man has four wives.
Like polygamy, but time-delayed.
I think people greatly underestimate how much high remarriage rates skew the entire marriage market. 40% of US marriages include someone who has been married before.
People just get married over and over, whilst many other people never marry. The whole thing is bizarre.
All of our romantic stories are about two singles meeting and marrying, but 2/5 times, at least one of them has already been married at least once.
Meanwhile, 25% of over-40 year-olds have never married and most of them are living alone.
Typical for polygamous societies is a high never-married rate, especially amongst men, and that's what we're seeing.
Tired of being seen. Just want to soak my way into single 40s 
According to Joseph D. Unwin who 1934 published a book called "Sex and Culture" dealing with the correlation between a society's level of "cultural achievement" and its level of sexual restraint.
His study of 80 cultures throughout history led him to the conclusion, that as cultures/societies develop, they become more sexual liberal, which leads to a loss of cohesion, impetus, and purpose. What inevitably follows is the succeeding decline of this culture/society.
He was probably thinking about Berlin.
I'll be frank.
I see no material difference between a Christian having two living spouses, that they've slept with one after the other, and a Muslim or Mormon doing the same. It's the same picture.
Time-delayed polygamy. Stealing that. It will probably make its way into a sermon.
Make sure you mention the stats. People often think it's an exception thing (especially in a conservative congregation, where everything still seems relatively normal) and it's like whatever, but when you hear the actual society-wide numbers, it's like daaaammmmmnnnn.
It may be partly an indictment on how incredibly shitty the State-default prenuptial contract is.
"2 kinds of clients: those who want bespoke prenups, and those who want a divorce"
(Heard from a close lawyer friend on multiple occasions)
Good point. Seem to need a divorce to regulate even mundane concerns, like how to facilitate mortgage payments.
