As the two royal ladies became increasingly unhappy with their marriages, they leaned on each other in the darkest of times. In her autobiography, Ferguson wrote that 1991 was the year they first started talking about leaving their husbands and the royal family.
It was the year we first put words to the unspeakable idea that had been nudging us in the ribs for some time: that one or both of us might leave the royal family. We burned the phone wires into the night, trading secrets and jokes that no-one else would understand.

But as it turned out, Diana wasn’t rushing with this decision.
But the Princess wasn’t planning to make hasty actions. Instead, she decided to use her friend’s marriage problems to her advantage. In her eyes, Fergie turned into a 'miner’s canary' that British miners used to use to detect methane deposits.
Using Sarah’s example, Diana wanted to see what would happen if she, too, decides to end her unhappy marriage. As the history tells us, both royal ladies separated from their husbands in 1992, which made them even closer at that time.
Interestingly enough, Sarah and Diana’s close relationship once made Prince Charles think they are plotting against him. The Princess of Wales wasn’t sure her estranged husband would be a good king, which made him think that Sarah and Diana planned to replace him and make Prince Andrew a Regent.
Since their separation, Diana and Fergie remained by each other’s side until they drifted apart later in life.
