Just out of curiosity (not my situation). Imagine the following scenario. A married couple with two kids is facing difficulties. To "fix" their marriage, they decide to have a third kid. Still marital problems. Then they decide to have a fourth kid (age difference between 1st and 4th kid is 10 years, fwiw). Still marital problems. They end up deciding to divorce.
I find this to be rather stupid and, to some degree, selfish. Why bring new kids to a bad family situation? Am I missing something?
