MineralMan has a good suggestion. Our church is full of people who are committed to one another in marriage. Some have been married over 50 years and they're still in love. I'm truly sorry your experience has been the opposite but they are still out there.

Sigh - for the last time my position is NOT predicated upon my own life but on what I've observed and read both here on FR and in other works.

That said, I would find it more laudable for a couple to remain together for such a long time if they were to get married today. Those who married 50 years ago did so in a society with vastly different expectations and morals.
