Prince Harry's recent return to the the U.K. was a huge wake-up call.
His appearance at Prince Philip's funeral on April 17 marked the first time home since he left the royal family, but he reportedly wasn't expecting to feel like such an outsider.
"We read that Harry was shocked by the frosty reception he got from some members of the Royal Family. Some literally turned their back on him," reported radio star Kevin O'Sullivan. "He was stunned by this — I'm not sure why that was a surprise to him."
"It must be occurring to him how frozen out he is, how he has turned his back on his former life," added O'Sullivan.
Aside from the shock, some presumed that seeing his family again made him reminisce on their happier days together.
"There is suggestion that when he came back a few weeks ago, he was reminded of his old life," he noted. "He felt rather nostalgic about it and he isn't so thrilled about his new circumstances as he wants you to believe."
At the moment, Harry is living in Montectio, Calif., with wife Meghan Markle, who's pregnant with a baby girl and is due this summer. They're also parents to son Archie, who turns 2 on May 6.
In a TV interview with Oprah Winfrey, the couple gave several reasons as to why they left the royal family, claiming they were ignored when they reached out for help regarding security concerns and their mental health.
The tell-all deepened the rift between Harry and his brood, and insiders say they are still far from forgiving one another for all that's happened.
