Then, very important in recent years, is the midlife marriage crisis. This is approximately at the 20-year point, when the children leave home, and many people pull out, typically men at this point because they're 45 or 50 and they realize they don't want to be married to this person for the next 30 years. Those are the phases. So, there hasn't been much change recently. It remains high.
Women have more choices than they used to.
There is less stigma to divorce than there used to be. It's accepted now in popular culture. Society has become more mobile. A partner in a marriage has to get along with his or her own parents. That's the major challenge.
