Kate Middleton and Prince William will never divorce while Queen Elizabeth II is still alive.

The Duke and Duchess of Cambridge have been married for eight years already. Prior to their wedding, they dated for almost a decade.

Earlier this year, there were rumors that Prince William cheated on Middleton with their family friend, Rose Hanbury. Despite the speculations, a source said that the couple is not splitting, but the rumors have rocked the palace and affected the pair’s marriage.

Amanda Harding also believed that it’s unlikely for Prince William and Middleton to get a divorce while the Queen is still alive because she wouldn’t allow it. Her Majesty could no longer stand another divorce after the high-profile royal divorces in the past years that included her sister Princess Margaret and three of her children Prince Charles and Princess Diana, Princess Anne and Captain Mark Phillips, and Prince Andrew and Sarah Ferguson.

The Queen is the head of the Church of England and has some say in what happens following those royal splits. Her goal is to avoid more divorces during her reign.

Prior to Prince William’s proposal to Middleton, the couple had an on-again, off-again relationship. The Queen warned the second-in-line to the throne when it comes to choosing his wife because “enough is enough,” the monarch said referring to the divorces that happened in their family.

“She now feels, to put it bluntly, that enough is enough,” an insider told Sunday Express in 2006. “She does not want to name names, but she is adamant that there are going to be no further royal divorces during her reign.”

It wasn’t difficult to convince Prince William to do what the Queen told him because he didn’t want his marriage to be the same as Prince Charles and Princess Diana’s. The Duke of Cambridge took his time and refused to be pressured to the altar.

It even came to a point when Prince Philip and Queen Elizabeth II had to give him an ultimatum about Middleton because at the time, they had been together for over five years already and he still didn’t propose. Middleton was already dubbed “Waity Katie” back then.

Prince William and Middleton got engaged in 2010 and got married the following year. Aside from the Queen’s potential objection, many believe it’s unlikely for the couple to divorce because they are happy together.
