It’s no secret that former President Barack Obama’s sun rises and sets on wife Michelle Obama. This exact sentiment was seen on Wednesday as he wished the former First Lady a 54th birthday on social media. On Instagram, he posted a loving throwback picture of the two with him giving her the most adoring look. “You’re not only my wife and the mother of my children, you’re my best friend. I love your strength, your grace, and your determination. And I love you more each day.
