You are assuming that unhappy marriages, or marriages that are merely a facade are in the best interest of the children. I didn't intend to get this serious in this thread, but since you bring up the topic of children -- The scientific consensus on the effects of unhappy marriages on children highlights several significant impacts. Children in homes with constant conflict or stress may develop issues such as chronic depression or behavioral problems. They often internalize their parents' conflicts, which can lead to low self-esteem and self-doubt. These children might blame themselves for their family's unhappiness and question their actions and worth.
When people say think of the children, what they are really saying is think of the idealistic and unrealistic attitudes of tradition.
Staying in a toxic marriage can cause more damage than good. Here's how:

I am a child of divorce. I don't know if it would have been any different on my psychological well-being if my parents had stayed together, but they were both alcoholics with mental health issues. Being raised by ****ed-up human beings will definitely have harmful effects, no matter if they stay together as a couple or separate.
However, I also would consider that materially, financially, and socially, I probably would have been far better off if they stayed together. Plus, the idea of stability, being able to go home to the same place - rather than be bounced back and forth between mother, father, and grandparents in different states, moving every few years, changing schools frequently. Having to go to school to explain to teachers and classmates why my parents don't live together in a time and place where such things were rare and considered shameful. Having people come to the door and asking "Is your mother home?" when she's 2000 miles away. Being shunned by neighbors, whose kids I'm not allowed to play with because reasons.
Granted, it would be better if children had parents who acted like mature human beings, who weren't so egotistical and full of hubris that they can't get over a little snit, suck it up, and bite their ****ing tongues for a little while. That would be better than a house full of conflict. Now that I'm adult, I've come to understand concepts like conflict resolution and parental abuse, things I could not understand nor process at a young age. But now I know that every conflict, every disagreement, every argument is resolvable, as long as both parties act in good faith and act like adults, not children.
