But by the beginning of the ’90s, Charles and Camilla were fully, if theoretically secretly, back on. And Diana was not the only one who assumed they’d been having an affair, according to The Prince of Wales. Charles’ closest friends suspected as much, as did “one or two members of his own family,” Dimbleby wrote, who warned the prince an “illicit liaison would be damaging to his own standing and to the institution of which he was so crucial a member.”
Charles told Dimblebly in a June 1994 TV interview that he wed Diana fully intending to be committed to his wife, and that he didn’t resume his romance with Camilla until their marriage was “irretrievably broken down, us both having tried.”
Camilla, Charles said, “has been a friend for a very long time and will continue to be a friend for a very long time.”
Diana told her confidante (and rumored former lover) James Gilbey, per Morton’s Diana: Her True Story in Her Own Words, “If I let it get to me I will just upset myself more. So the thing to do is to involve myself in my work; get out and about. If I stop to think, I’ll go mad.”
