Earlier quoted context omitted.
I find this to not be a helpful frame of thinking. A divorce is not a random natural disaster that befalls you. You have a lot of control about who you end up with, who you are inside and how you engage with your partner. So the fact that divorce happens "often" or "rarely" doesn't matter to an individual scenario - it's completely within those people's controls to make good or bad decisions.
Divorce happens often and the rates are climbing. It makes sense to follow statistical guidelines. "Who you marry" is not in your control. People change over the years. Marriage changes your spouse, and yourself. Some people realize what they actually want as they mature. Most of the smartest, most thoughtful people in the world get divorced. They all thought they had control over marriage.
There's a huge difference between "not at all" or "not fully" in my control. I can't guarantee my outcome, but I have deep influence over my chances.
