He told The Mirror: “As time goes by, Harry misses some aspects of his old life in the UK.
“Inevitably, the honeymoon period where everything in the States is new and exciting is coming to an end and Harry is looking back at the past through rose-tinted spectacles.”
Mr Quinn believes Harry now wants a permanent home in the UK.
He added: “He misses his Old Etonian and army friends, many of whom have not visited as they don’t get on with Meghan.
“Harry is determined to find his own permanent home in the UK, which is partly why he’s continuing his legal action to get the British taxpayer to pay for his security.”
In his memoir, Spare, Harry admitted that he always planned to stay in the UK.
Referring to Frogmore Cottage, his former royal residence, Harry wrote: “Once upon a time, this was going to be my forever home. Instead, it had proved to be just another brief stop.”
In recent months, there have been reports suggesting that Harry wants to build bridges with his family, especially his father King Charles.
Phil Dampier said on The Sun’s Royal Exclusive show: “They’ve got new PR people and if they listen to their PR people – sometimes people don’t listen to their PR people – but if they listen to their PR people, I’m sure they’re telling them that right, you’ve made your point, you’ve had Spare, you’ve had Netflix, you’ve had the Oprah Winfrey interview, you’ve got it all off your chest.
“Now’s the time to row back a bit and try and build some bridges or at least create a life for yourself.”
Harry’s relationship with his brother, Prince William, remains broken after William allegedly branded Meghan “rude” and “difficult” before allegedly pushing Harry to the ground during a row in 2019, as Harry claimed in his memoir.
