Real marriages are all lived within not without. What is going on inside of it that others do not see. That is where the people live.
How often have you been shocked at separations of those who seemed ideally suited to be together forever?
Likewise how many times have people stayed together till death did them part that you knew wouldn't last but it did?
Some adore each other till death them do part. Some abhor but stay together for financial reasons or whatever and actually live separate lives on separate tracks but give the ilusion of a good union.
Go FIGGER!
