The happily ever after trope goes something like this:  Love, marriage, children, happiness.   However, that is not what the statistics show.  “Parents often become more distant and businesslike with each other as they attend to the details of parenting.”  The source of this sad passage is “Decades of Studies Show What Happens to Marriages After Having Kids,” in Fortune Magazine. The statistics show that having children drives a married couple apart more than it brings them more closely together:

The irony is that even as the marital satisfaction of new parents declines, the likelihood of them divorcing also declines. So, having children may make you miserable, but you’ll be miserable together.

Worse still, this decrease in marital satisfaction likely leads to a change in general happiness, because the biggest predictor of overall life satisfaction is one’s satisfaction with their spouse.
