This article considers only the people whose aim in relationship is to aid in their lonliness, find someone to be with, blah blah. What about those who want to have kids, and a family. I dont think anyone will have the same line of thought after having kids.
The goals may change, but lots of people leave their spouse even after having kids, so it's not a perfect guarantee. Not saying that is right, or desirable, but it's definitely something that happens.
It's too early to tell what the effect will be on these kinds of couples. Even with kids, you go through phases, and life at age 1 (for the children) is vastly different than at age 21
