The Duchess of Cambridge will have spent a decade as an HRH when she and the Duke of Cambridge mark their 10th wedding anniversary on Thursday.
Kate became a future queen when she married second-in-line William at Westminster Abbey on April 29 2011 after an eight-year relationship.
But an ‘anxious’ William confided in Charles and Queen over doubts about future with Kate, it has emerged.
Royal expert and author Katie Nicholl said William had become so anxious he confided in Prince Charles and the Queen.
The latter was reportedly disappointed by the decision to break up with Kate.
She said: “William had been having second thoughts and sat down with his father and his grandmother to have a frank discussion about his future with Kate.
“Both advised him not to hurry into anything.”
In their first year in 2001, William and Kate lived a few doors apart at St Salvator’s hall of residence at St Andrews in Fife.
The pair – who would marry in 2011 – became friendly, socialising together and playing tennis, according to royal insiders.
She captured his attention in March 2002 when the prince forked out £200 for a front-row seat for the fashion show where Kate appeared in a see-through lace dress which revealed her black underwear.
Kate, who is five months older than William, was credited with persuading him to continue his studies when he found it difficult to settle.
William had considered quitting in his first year, it has been widely reported in the years since.
