Princess Diana allegedly dropped a telling sign that her marriage to Prince Charles isn’t all that it seemed two years before they separated.

On Valentine’s Day in 1990, the late royal talked about marriages during her engagement. Princess Diana said that marriage offers stability that’s why nearly 7,000 couples a week start new family lives of their own.

But the Princess of Wales also acknowledged the fact that for many of these marriages, reality fails to live up to expectations.

According to New Idea, royal fans didn’t think anything of Princess Diana’s statement. But this might already be her way of dropping a clue that she isn’t happy in her marriage to Prince Charles.

Two years after her speech, Prince Charles and Princess Diana announced their separation. And four years later, they divorced was finalized.

One of the reasons behind the couple’s split was Prince Charles’ affair with Camilla Parker Bowles. During her interview with Martin Bashir for Panorama, the mom of two said that her marriage became a little bit too crowded because there were three of them in the relationship.

Prince Charles eventually admitted to having an affair with Camilla during his interview with Jonathan Dimbleby in 1994. The future king said that he was always faithful to Princess Diana until their marriage became irretrievably broken down.

The dad of two also said that he and Princess Diana both tried to make their marriage work. However, they just couldn’t do it.

In the book The Firm, The Troubled Life of the House of Windsor, royal author Penny Junor said that Prince Philip was incensed when he heard his eldest son admit his affair with Camilla.

Junor said that a lot of people thought that Prince Charles’ admission was the biggest mistake of his life. After all, they thought that the admission would cost him the throne, but it didn’t.

Meanwhile, Prince Charles and Princess Diana sounded very optimistic at the start of their marriage. Four years after they tied the knot, the Princess of Wales vowed to always support her husband.

Prince William and Prince Harry’s mom said that her role is supporting her husband whenever she can. Princess Diana also said that she will always be behind Prince Charles to encourage and love him.

Following the couple’s divorce, Princess Charles and Princess Diana reportedly cried on the sofa because they were sad that their marriage was over.

A year after their divorce, Princess Diana died following a tragic car crash in Paris.
