Meghan Markle was reportedly "hugely disappointed" with life in the Royal Family and struggled to adjust to the new set of rules that came with her position.
The Duchess of Sussex, 41, is thought to have "hated" being told what she could do and had a "great divide" between what she expected of royal life and the reality.
Royal biographer Tom Quinn said Meghan had been "dazzled" by the prospect of becoming a Princess, but was less keen when she realised her life would be dictated by the royal household.
