We have Jean on the line from Devon. Her parents postponed divorce several years for the sake of the children. Maybe Jean can add something to this conversation. My parents were married for 25 years before they actually got divorced. They first discussed it when I was about 10 years old, but they didn't go through with it until I was 21.
People often talk about staying together for the sake of the kids.
But I think that with my parents, it wasn't so much a matter of staying together for the kids, as staying together because of the kids. My siblings and I were a common bond for my parents at a time when they didn't have much else in common. There were five of us, so we were the central focus of their lives. It was easy for them to lose the personal priorities of their relationship in the chaos and excitement of five kids. When my parents finally went through with the divorce, I was older and I had seen a lot.
