Familes that are still together

I'm divorced, but my parents and grandparents were all married for over 50 years. My siblings have also been divorced and remarried at least once. I know it seems that divorce is more common now than with the older generation but I think a lot of those never divorced even though they were unhappy in their marriage and divorce was frowned upon. These days, happiness is considered more important than keeping a marriage going no matter what.
