Michelle and Barack Obama

The former US president and first lady's marriage became fractious after the couple welcomed daughters Malia, 25, and Sasha, 22 and Michelle discovered that therapy helped her to find happiness again.

Speaking in her Netflix documentary 'Becoming', she said: "Counseling helped me to look at, 'How do I take control of my own happiness within our marriage?'

"One of the things I learned that helped me and I think helped our marriage was that my happiness is not dependent on him making me happy."
