It's amazing to me that western democracies seem to facilitate single parenting and divorce, instead of discouraging it.
Because alternative is often quite a lot of suffering of one or both parties.
Even beyond abusive/controlling/openly hostile relationships, you have people who completely checked out of marriage long before divorce. Their partners finally calling end to it are just putting paper on what was reality before.
The thing about traditional marriages with low divorces is that abuse whether physical or verbal was a fact of life in many families. It also often meant alcoholic or gambling partner for years, it meant couples that looked down at each other. Nowdays alcohol was replaced by gaming all the time in some couples, which is milder, but still fully understandable.
And porn.
I mean, even divorced parents tend to try to live close to each other. Why wouldn't amicably arranged co-parents not opt for the same if that means easier parenting and living costs?
