Princess Diana had been honest with her son, Prince William, when it came to Prince Charles and Camilla Parker Bowles’ love affair.

In an interview with BBC’s Martin Bashir in 1995, Princess Diana explained how she told Prince William about the real issue with her relationship with his dad, Prince Charles. The Princess of Wales didn’t forget to mention the future king’s affair with Camilla, but she did it without blame and anger to make it easier for the Duke of Cambridge to accept.

The People’s Princess recalled how Prince William asked her what had been going on with her and Prince Charles. Princess Diana told her eldest son that “there were three of us in this marriage“ and the “pressure of the media” took its toll in their relationship. The two issues were “very difficult.”

Princess Diana also told Prince William that she still loved his father. However, she couldn’t live under the same roof as the Prince of Wales.

“He's a child that's a deep thinker, and we don't know for a few years how it's gone in. But I put it in gently, without resentment or any anger,” Princess Diana said.

Prince William also learned that Prince Charles was pressured into marrying Princess Diana because she was the perfect “virginal” bride for the heir. It seemed that the Duke of Cambridge was keen not to repeat his parents’ mistake as he was very upfront that he didn’t want anyone to pressure him to the altar.

Prince William was adamant about marrying Kate Middleton. In fact, they dated for almost a decade before they finally decided to tie the knot.

In 2004, three years after they started dating, there were rumors that the second-in-line to the throne would propose to his girlfriend. However, Prince William ended the rumors, saying that he was only 22 and had no plans to get married until he is 28 or 30.

True enough, Prince William took his time. The couple only announced their engagement in 2010. Due to Middleton’s long wait, many dubbed her as “Waity Katie.“ However, she had the last laugh because in the end, she got her prince.

According to royal biographer Katie Nicholl, Prince William promised Middleton that he would marry her after their second major split. Both agreed that they would end up together, so Middleton didn’t mind waiting for years because she knew they would end up in the altar together.
