I am fortunate in that my Grandparents all made it past 60 years of marriage, with my wife's grandparents celebrating 62 years this week. My parents are at 55 years, and my wife's parents are at 40 years. And whenever someone says they have been married over 25 years, I make sure to tell them that it is an accomplishment to be proud of.
Sadly though, this is 2020, and being on our church's DivorceCare Leadership Team we are privy to statistics, and sadly "Gray Divorces" are not just on the rise, they have the greatest number now compared to people married lesser years.
When I was going through my divorce, a guy I worked with was just like you, boasting how many years he was married, and how the rest of us were quitters. Then his wife of 32 years left him for a man she met on the internet. He was crushed.
But that is how life can be. "Pride goeth before a fall", as the bible says, so beware.
