There are couples (probably your grandparents) that have been married for 40, 50, 60 years.
And that's a beautiful thing.
But a lot of people today aint with that "in sickness and in health....in good times and in bad" promise.
Marriage today is "til death to you part.....or until I'm unhappy or bored...or if you cheated"
You know how difficult it used to be to get a divorce?
I'm not saying people didn't split up back in the day. But they definitely tried way harder to stick together.
