I think the divorce rate is not about age or sheltered-ness. I think it is about how we raise our kids. Our kids are growing up in a world were everything is on credit and little is toiled for. If we can’t afford it, we charge it. If we can’t charge it, we refinance. If we want it, we buy it RIGHT NOW online. If it is the wrong price, we bizrate quote. Bored? go online. Nobody answering the phone? message them. Parents yelled at you? text a friend.
When your world works like that, it is very hard to develop a value system that includes delayed gratification, compromise and time alone with yourself to determine who you are and how your behavior affects others.
I know friends who get in fights with their spouse. In the past, they would be left alone to process the fight or they may call a friend . Now they get online and ask a chat room full of people for their opinions and support. Or they get online and distract themselves til the pain goes away. The fundamental relationship developing skills are dwindling.
