"Marriage flourishes when the couple works together as a team; when both husband and wife decide that winning together is more important than keeping score. Good marriages don't just happen. They are a product of hard work."
Indeed the love between this pair continues to burn bright, with Barack taking to Instagram to profess his adoration for Michelle, 54, with a birthday message that we're sure melted our hearts along with Michelle's.
"You're not only my wife and the mother of my children, you're my best friend," he posted, along with a picture of the two sharing a tender moment together. "I love your strength, your grace, and your determination. And I love you more each day."
Michelle lovingly responded: "You're my best friend, biggest fan, and getting notes and flowers from you will never get old."
