After Princess Diana and Prince Charles split over his affair with Camilla Parker Bowles, the Princess of Wales reportedly sought comfort in the arms of her married boyfriend, Oliver Hoare. Their complicated relationship resulted in Diana receiving a warning that she did not appreciate.

Once Prince Charles and Princess Diana realized their marriage was over, she began searching for love. However, her healer revealed she shared her disapproval about Diana’s relationship and advised the royal to let go of the romance.

Simone Simmons told the Daily Mail, Diana was aware her relationship with Hoare would fail. “I would tell her the feedback I was getting at our sessions, often about her relationships; she didn’t always want to hear what I had to say, but I told her anyway,” she explained.

Princess Diana was allegedly unhappy about Simmons’ pessimistic outlook. “‘You don’t have to say it like that,’ she would say. And I would reply, ‘But there’s no other way of saying it.’ I was very blunt,” the healer revealed.

“I told her there was someone in her life who was no good for her, who treated her like another notch on his bedpost – that was Oliver Hoare. I told her that she shouldn’t expect him to make any commitment to her and she looked at me daggers.”

According to royal biographer, Sarah Bradford, Diana’s refusal to give up on her relationship with Hoare reportedly resulted in dramatic arguments. “One evening, his wife was away, so Oliver had to be with their sick daughter,” she revealed.

However, the Princess of Wales was convinced Hoare was lying. “Diana was so jealous that she suspected it was an excuse to see his wife so, as he was driving her home she jumped out of the car in a traffic jam in Sloane Square and disappeared,” Simmons said.

“Oliver was so worried he spent three hours driving around looking for her and never got to see his daughter. He finally found Diana crying her eyes out in Kensington Gardens.”

Princess Diana’s romance with Hoare eventually came to an end, and she began dating Dodi Fayed. Their romance and lives came to an end in 1997 when the two died in a car crash in Paris.
