Prince Harry said in yet another interview Monday that his late mom, Princess Diana, would be “heartbroken” at the way his bully brother, Prince William, betrayed him.

“I think she’d be sad,” the 38-year-old exiled royal told Michael Strahan on “Good Morning America” when asked how his mom would feel about the total breakdown of his once-close bond with his brother.

“I think she would be heartbroken that it’s ended up where it’s ended up,” he said.

Harry theorized that specifically, his mom would have been pained to see 40-year-old heir apparent William allowing his PR people to endlessly trash Harry and his wife, Meghan Markle, with planted stories.

“I think she’d be heartbroken about the fact that William — his office — were part of these stories,” he said of the negative press he widely blames for forcing him to flee his family and his homeland.

“William and I made a pact, made a deal, that no matter what, we would never let offices fight against each other,” he said, answering “yes” when asked if he felt his brother “broke that pact.”

“The people that he employed broke that pact,” he stressed of his brother, whom he has accused of battering him and bullying him out of the family.

In a rare moment of self-acceptance, Harry conceded that “without question” he was “sure” he had at least some responsibility for the breakdown of his relationship with his brother.

“But what people don’t know is the efforts that I’ve gone to, to resolve this privately, both with my brother and with my father,” he said of William and their dad, King Charles III.

That, he claimed, justified him now constantly trashing them in public, most notably with the multiple revelations in his new memoir, “Spare.”

“I don’t think that we can ever have peace with my family unless the truth is out there,” he said, defending his brutally revealing memoir after years of complaining about a lack of privacy.

“There’s a lot that I can forgive, but there needs to be conversations in order for reconciliation. And part of that has to be accountability,” he told the ABC News breakfast show.

Despite his endless trashing, Harry claimed: “I love every member of my family.”

That includes his stepmom, Queen Consort Camilla, whom he begged his dad not to marry and whom he accused in “Spare” of having “sacrificed me on her personal PR altar.”

“I have a huge amount of compassion for her, being the third person within my parents’ marriage,” he said, referring to his late mom’s famous description in a BBC interview about mutual cheating during her time with now-King Charles.

“We haven’t spoken for a long time,” he said of his stepmom, claiming that when they do meet, he is “perfectly pleasant with her.”

“I don’t look at her as an evil stepmother,” he said of a much-noted section in his book.

“I see someone who married into this institution and has done everything that she can to improve our own reputation and her own image for her own sake,” he said.

Harry claimed that his decision to quit his family did not upset or even anger his grandmother, the late Queen Elizabeth II.

“My grandmother and I always had a very good relationship. It was never a surprise to anybody, least of all her,” he said of his exit.

“She knew what was going on — she knew how hard it was. She never said to me that she was angry. I think she was sad that it had got to that point,” he said.

Questioned over critics who said his Netflix series and memoir let him profit off his family’s pain, Harry claimed he was merely protecting his family by sharing the truth.

Still, he conceded: “I fully accept that writing a book is feeding the beast.”

He also conceded that he is unlikely to give up his swanky life in California to return to the UK and life as a working royal.

“I don’t think it’s ever gonna be possible,” he said, suggesting that even if he reached an understanding with his family, “there is that third party that is going to do everything” to make it “unsurvivable” for them.

“And that’s really sad because that is essentially breaking the relationship between us,” said Harry, shifting the blame from his own shocking accusations and revelations.

However, Harry, who remains the Duke of Sussex, claimed that there was no possibility of him actually fully walking away.

“I can’t ever get out,” he told Strahan.

“I’m incredibly aware of my position, and I’m incredibly grateful for the life that I’ve had and continue to live.

“But there’s no version of me being able to get out of this,” he claimed.
