Here is an interesting article from when Charles was turning 40 - in October 1988. Right at that 'crucial' moment in the marriage that we are very much aware of now. Some interesting text from the article follows the link -

At 40 Prince Charles Is Drifting Away from Diana and His Two Sons into a Separate Life
Even in October 1988, it was recognized:
"He has a record of achievement unmatched by any other Prince of Wales in British history."
He was getting some very good press - we tend to forget in the way dust gets kicked up to cloud history:
"Add to all that: ruddy good health, scorching charm, lively wit, ever-ready virility and a flair for the arts—he paints, pots and plays the cello with admirable skill. What more could a man want?"
He has held a steady course:
"Yet time and again this monarch-in-waiting has charged into dangerous terrain. Charles has championed scholarships for the poor, raised financing for start-up businesses and launched a nationwide campaign to protect the environment. "I don't just want to be seen trundling around," he has said. "I want to be involved in something that makes a difference." "
Significantly:
"At times the prince's initiatives have irritated the supremely irritable mistress of No. 10 Downing Street."
I have long had the suspicion that those bizarre leaked conversations between Camilla and Charles - recorded over a long period and patched together, was the work of some very malicious intent, someone keen on denigrating the monarchy - and Charles in particular. The then 'mistress of No. 10 Downing Street' has more than once crossed my mind as the initiator of that nastiness.
"Despite his achievements, Charles seems to agree ruefully with biographer Holden that his existence is essentially "a comfortable form of inherited imprisonment." "
"When asked how he sees himself he may answer with a wry smile, "Sometimes, I suppose, as a bit of a twit.""
Fascinating, it then begins the litany that already then was gaining steam. But what is of note here - and that revisionist social historians forget is that Charles always demonstrated love and caring of Diana - it was noticed and notable:
"Problems in the prince's marriage have added to his malaise. His once burning passion for Diana has faded to a chilly cinder, and the tender father who changed William's nappies and pushed his pram has hardened into a quasi-delinquent parent. "When the going with the children gets tough," says one close observer, "the prince gets going." Over the last year, Charles has spent long periods away from Diana, and it is now tacitly understood in royal circles that he has sought out the company of other women."
Dealing with the tragedy at Klosters and the death of his friend:
"Charles's admirable grace under pressure disarmed his detractors."
Then there is a litany of his negatives that we know all too well now - endlessly repeated without any of the good noted, but this insight - that we very likely have the Prince of Wales we have because of Mountbattan:
"At Mountbatten's insistence, Charles became the first Prince of Wales to complete a university education. ("I'm one of those stupid bums who never went," Philip grumped, "and I don't think it's done me any harm.") [...] Graduating at 21 with a respectable "second" in history."
There is this on his series of girlfriends - written in 1988, there is nary a mention of Camilla Shand:
"Most of Charlie's Angels (as the press called the ladies he dated) were high-born British beauties who traveled in his own smart set: Davina Sheffield, Fiona Watson, Camilla Fane and Lady Jane Wellesley. However, the grand passion of the prince's youth—the one woman he desperately wanted to wed—was Anna Wallace, a sexy Scottish lass with a rip-roaring sense of humor. Alas, Anna also had a fiery temper—not for nothing was she known as Whiplash Wallace—and one night at a palace ball it blew their affair to flinders. The prince carelessly ignored his ladylove for several hours, and when at last he went looking for her she was gone—forever. Charles was devastated."
There is this bit of evidence of just how harrowing it was to have Philip as the disapproving father:
"All things considered, Charles's military record was slightly better than his father's. Was Philip satisfied? Not for a minute. He continued to label his son "wet" (British for wimp) and to invent sadistic ways of "toughening him up." Just after Mountbatten's assassination, for instance, knowing that Charles was stricken with grief, Philip harped on the horrible event at the dinner table until Charles burst into tears. "Perhaps now," Philip sniffed, "he won't cry at the funeral." "
Here is an interesting summary of Charles and Diana's courtship and early marriage - again, revisionist social historians - like some Diana Fans I've encountered - fail to understand that Charles and Diana did share a love, despite her re-spin of their early married life:
"Diana caught him on the rebound. As a schoolgirl she had kept his picture pinned above her cot and once confessed to a friend, "I would love to be Princess of Wales." Hope got a boost when he began to date her sister, and when in turn he asked her out she was in seventh heaven. Charles was in despair. With Anna gone, he wondered if he would ever find a woman he loved enough to marry. One day he asked Queen Mother Elizabeth what he should do. Well aware that Diana adored him—and that older, more worldly paramours often had romantic histories that made them unacceptable to the palace—she made a historic suggestion.
And so the wheels of courtship began to turn. Diana was in love, Charles was in business—the business of sustaining the dynasty—and he was brutally truthful about his motives. When asked if he was in love, Charles made a face and replied churlishly: "Whatever 'in love' means." For almost a year he watched Diana as a director watches an actress reading for a part, and he was impressed. She had everything he needed in a wife and a queen: looks, moves, background, temperament. She was spirited, energetic, affectionate—and a virgin. So he gave her the job. It was almost as coldly calculated as that.
But something happened on the honeymoon. The man who came home from that two-week Mediterranean cruise had been shot through the heart by Cupid's arrow. He radiated a joy that persisted for several years. Charles was right by Diana's side when William arrived, and for a time he doted like a nanny. "He knows so much about babies," Diana teased. "I think he should have the next one." But by the time the next baby showed up, the splendor had faded. Charles was present when Harry was born, but immediately after the delivery rushed off to play polo."
Interestingly, that Charles was wandering was a matter of fact, not speculation, in 1988. In a discussion of Charles' possible amours at the time, several married women are mentioned (never Camilla). However, this is said of Diana, when we now know that at the time (1988) she was in her head-over-heels love affair with James Hewitt. Were Diana to have an affair she would risk her marriage - which was one of the reasons I thought the divorce happened, because she admitted publicly - to the nation - to being in love ("I adored him") and having an affair while married to the heir to the throne. The double standard is unfair but there it is:
"Diana herself is considered unlikely to start an affair. "Her position as Princess of Wales means more to her than anything in the world," says a friend. "There is no way she would risk this for a silly fling." "
Poignantly, the article ends with the promise of one or two more children - perhaps a little princess. What a different world it would have been for all concerned had that, in fact, happened:
"So what lies ahead for these star-crossed prisoners of privilege? Some friends of the royal couple maintain optimistically that the marriage has "bottomed out" and that "things can only get better." They may be right. Diana appears to be looking ahead with a measure of hope. "I'd love a daughter," she chirped some months ago. "You can dress them in such pretty clothes." And Charles, though he mutters sourly that "two noisy boys are enough," is known to want two more children. "Now that Fergie has had her baby," says a friend of the family, "Di may soon become pregnant again." That might resolve matters for Diana—if not for Charles. At 40, some men pull themselves together. Others lose their way. It's a dangerous age."
