I read somewhere that of all the stressors on a marriage, having a child is the biggest. It’s bigger than losing a job, bigger than getting sick, bigger than the death of a parent, bigger than one side cheating on the other, the works.
The only event more stressful on a marriage than having a child is having a second child. Supposedly, anyways. I guess kid No. 3 isn’t such a big deal, though. I guess by that point the guy has probably already figured out that he’s in it for the duration whether he likes it or not. Might as well make it work.
