The Duchess of Cambridge helped save Prince William after he left his 'dysfunctional family' by making him 'feel important and worthy', according to a royal expert. Angela Levin, author of Harry: Biography of a Prince, told True Royalty TV's The Royal Beat that the Duke of Cambridge, 38, was in a 'very difficult place' after losing his mother Princess Diana aged 15 in 1997. The young prince also witnessed his father, the Prince of Wales, and his mother's very public breakdown of their marriage before their separation in 1992. Ms Levin claimed Kate, 39, who married William on 29 April 2011 at Westminster Abbey in London, 'really encouraged' the duke and has dedicated her 'whole life to making him happy'.
