For better or for worse, in sickness and in health, until death do us part.
But just how sacred are these wedding vows?
Michael Douglas, 68, and Catherine Zeta-Jones, 43, long considered a Hollywood royal couple, are taking a break from each other.
I was taken aback when I saw the headlines. The husband was equally shocked when I told him.
"Haven't they been together like, forever?" he asked.
Zeta-Jones' publicist, Cece Yorke and Douglas' publicist, Allen Burry, confirmed to USA Today in a statement that the two "are taking some time apart to evaluate and work on their marriage".
Perhaps in Hollywood terms, 13 years is a long time to be married.
That made me think. Have I been married, like, forever too? I'll be celebrating my ninth wedding anniversary in two weeks.
Have we encountered problems in our marriage?
