Eighteen year of marital bliss sure look good on Pat and Emmitt Smith.

To mark the special occasion, Pat, a published author and journalist, and her longtime love swapped sweet messages.

On Sunday, Pat took to Instagram to share a loving note in honor of her NFL Hall of Fame hubby and the work they’ve done to maintain their love over the years.

“The best marital advice I received was from a couple going through divorce- Keep servicing your marriage just like you do your vehicles. Don’t wait until it’s breaking down to go in for service!!!,” her caption began.

The author and mother of four continued, “We took that advice seriously!!! We struggle just like all couples and when we get weary we fight even harder to stay together!! We have always sought advice from wise counsel!!! Marriage can be really difficult, but with God, it can truly be phenomenal!!! 18 years and counting!!!!! Praise God!!!! I TRULY LOVE THIS MAN….MY HUBBY”

The Smiths married in 2000 and have three children together–sons Emmitt IV and Elijah, as well as a daughter, Skylar. Both Pat and Emmitt have daughters, Jasmine and Rheagan, from previous relationships.
