One other thought on this subject...most people don't question their lifelong committment to their children. Regardless of the rough spots, depression, and disillusionment we experience as a result of our lives with our children...nobody would ever think of divorcing their children. That's absurd. We learn to roll with punches. People have committed, all-forgiving attitudes toward their children...but when their spouses don't live up to their expectations...divorce is considered as an option!
Why?
