The Princess of Wales revealed that she felt incredibly alone during her marriage to Prince Charles and struggled with mental health issues for years. When this compounded with their 13-year-age gap and Charles’ affair with Camilla Parker Bowles, their marriage broke down entirely and ended in divorce. This was hugely damaging to the monarchy and contributed towards 1992 being branded “annus horribilis” by the Queen herself.
When it came to Kate, the Palace was determined not to have a repeat of the Charles-Diana marriage, where the bride was desperately lonely and cut off from her family, so they took steps to make sure this did not happen.
The Duchess of Cambridge has maintained strong connections with her own family ‒ her parents Michael and Carole, and her siblings Pippa and James ‒ who have been warmly welcomed into the fold themselves.
Now, Kate is a confident public figure, wife to Prince William and mother of three, and the Cambridges' marriage has helped strengthen the monarchy.
Royal commentator Katie Nicholl explained this in the 2017 ITV documentary ‘Kate: The Making of a Modern Queen’.

She said: “I think very much there is a feeling in the Palace that they want to learn from the mistakes of the past and didn’t want a royal bride who felt isolated and lonely and cut off from her family and miserable.
“Because that has happened before and they didn’t want a repeat of Diana.
“So I definitely think courtiers were determined that Kate should marry into the family feeling as comfortable as possible.
“And I just dont think William was going to take any chances ‒ I mean, he adores the Middlestons; he has a very close relationship with Michael and with Carole, so he also did not want them to be sidelined as soon as Kate married into the family.”
