Kate The Great: Her Singleton Years
It took Prince William only a few weeks in 2007 to realize that he wanted Kate and only Kate. "It wasn’t long before William was having second thoughts," Marcia Moody wrote in a new biography about the Duchess of Cambridge. "Mindful, perhaps, of the decision his father had made when he was in his 20s and failed to marry his early love Camilla, William did not want to make the same mistake. Kate, however, needed some convincing. He had broken her heart and she wanted to make sure that if they did get back together it would be for the right reasons, and that things would change."
