Kate Middleton has provided Prince William with everything "that was lacking in his own family life," according to a royal expert.
The couple's tight knit bond is a huge contrast to the emotionally unstable home in which William was raised in by King Charles and Princess Diana, former BBC royal correspondent Jennie Bond claims.
She told OK! that the Princess of Wales has given William all the things he didn't have with his royal relatives including a 'loving, deep partnership, founded on friendship, passion, and mutual respect, plus a broader, settled and happy relationship with his in-laws."
Ms Bond explained: "Michael and Carole Middleton welcomed William into their home and treated him like one of the family.
"He can relax with them, trust them, and be himself in a way he can do with only a very few others", the Mirror reports.
Kate and William celebrated their 12 year wedding anniversary in April and have been together since 2001 where they first met in student halls at the University of St Andrews.
William's relationship with Kate has outstripped that of his relationship to his late mother Diana who died when he was just 15-years-old.
Jennie, BBC's royal correspondent for 14 years, added: "William is much closer to his father these days, but I think it’s the women in his life who have helped make him the man he is.
"His grandmother, the late Queen, was there for him – as he said – through the happiest and saddest times of his life.
"His mother’s influence is still very much evident in the relaxed and informal way he interacts with people, and in his determination to help people less well off than himself, in particular, the homeless.
"It was, of course, Diana, who first showed her sons the plight of homeless people.
"Now, William has said that he wants his own children to be fully aware of how privileged they are and how other people may sometimes need a little help."
A charity boss said last week that Prince William's bid to help the homeless has seen him follow in Princess Diana's 'authentic' footsteps who carried a lot of her own charity work.
The future King has been focusing on raising awareness around issues of homelessness for a number of years.
Bond continued: "And then there is Catherine’s influence: they have known one another now for more than 20 years – longer than William knew his own mother – and she has won not only his deep love, but his respect.
"He might feel a little aggrieved when he is cut out of pictures at events they both attend, but he is proud of his wife for the way she has made such a success of the role that came with marrying him."
