Mr Lacey wrote: “A rising actress, Cressida did not enjoy the critical remarks that she could hear people making behind her back when she walked down the street in London.
“She felt that the fame of her relationship put her ‘in a box.'”
He added: “In 2014, she was said to have been ‘completely spooked’ after watching the TV coverage of William and Kate touring New Zealand with baby George in tow.
“That was not the way she would want to enjoy her eight-month-old son, she regretfully explained to Harry.”
Harry and Cressida parted amicably shortly after, saying in a statement: “It’s very sad that they have decided to split but this is a completely amicable separation and they are remaining the very best of friends.”
Despite the breakup, Cressida and Harry remained close friends and the actress was later invited to his wedding to Meghan Markle a few years later.
A previous serious girlfriend, Chelsy Davy, was also believed to have given Kate and William’s relationship as a reason to end her dalliance with Prince Harry years earlier.
Commentator Katie Nicholl claimed the Duke and Duchess of Cambridge in 2012 clinched the deal for Chelsy about her future as a potential member of the Royal Family.
Ms Nicholl said: “Being part of the royal wedding had made Chelsy’s mind up once and for all.
“The life of a royal bride was not for her and she told Harry she could never make the sacrifices Kate had made.”
Friends of Chelsy told the author the relationship was genuine and she “truly loved” Prince Harry but she ultimately had to accept she would not be able to cope with the constant spotlight.
Ms Nicholl added: “It was just after the royal wedding when she realised she couldn’t cut it.
“She saw what it would be like in the spotlight, and she didn’t want that life for herself.
“She truly loved Harry, but knew this wasn’t a life she could lead.”
While still active in the public sphere, Prince Harry also chose to distance himself from the attention of royal life and announced he would step down from his role as a working royal in March.
The Duke and Duchess of Sussex settled in Los Angeles shortly after their departure from the UK and have since struck several public speaking deals while trying to establish themselves as independent private workers.
