Latest news:Royal Expert Says Prince William “Inherited” King Charles’s “Fear of Commitment,” So Kate Middleton “Agreed to Wait for Him” details below .

Kate Middleton and Prince William tied the knot on April 29, 2011, in a fairytale wedding at Westminster Abbey. However, the path to marriage wasn’t totally smooth for the Prince and Princess of Wales, who weathered a high-profile split in 2007.

And according to one royal expert, William inherited some serious trepidation about committing to marriage from his father, King Charles.

In her book, The Making of a Royal Romance: William, Kate, and Harry—A Look Behind the Palace Walls, royal expert Katie Nicholl shared that the Prince and Princess of Wales took a trip to the island of Desroches in the Seychelles in August 2007, soon after getting back together.

“With a population of just 50 and 3 miles long, the paradise island was the perfect escape,” Nicholl wrote (via the Daily Mail). “[B]oth of them knew that at some point they had to discuss the future.”

Nicholl continued, “For a young man who has an inherent fear of tomorrow, this was not easy for William, but the tranquil backdrop of the island was as good place as any to discuss it.”
