sorry but I'm in shock here, your main source of information is a TV program!!!! One where there is minimal serious research done and is made as a populist program for an entertainment channel! And yes the books that have been written about "the war of the Wales" do base their information on the book by Andrew Morton that Diana contributed to.
If you want something more credible to read, read the archival newspaper and magazine articles from the late 70's to mid '80s. Also read Stephen Barry's book "Royal Service" which when first published was banned in the UK. Stephen Barry was Charles' valet and accompanied him everywhere, including his honeymoon. The book was published in 1982 and Stephen Barry died before the marriage of C & D disintegrated. He was on the royal train and clearly states that the woman wasn't Diana, not Camilla either. On the honeymoon Diana had a great time, she wasn't upset, there were no pictures of Camilla. Charles didn't do anything for himself, the valet organises and packs everything, he would have seen pictures if there were any. Also Stephen woke Charles the day of his wedding, no Camilla anywhere near him so that's a false story too. Stephen Barry did state that it was impossible for Charles to have women sleep over at Buckingham Palace as Charles' rooms were along a corridor (no interconnecting doors) and there was no way for a night-time partner not to be noticed by the staff. He also stated that in the 12 years he worked for Charles and his first job in the morning was to wake Charles, he was always in his bed alone. The cuflink story also has no credibilty as Charles' staff would have been the ones to order them and buy them, it didn't happen. This story is attributed to Diana. Please do some serious research ( not just populist TV programs or books with no historical research, look at the sources they use).
Charles had 2 very close woman friends, Camilla and Dale Tynan. Both are mentioned throughout his dating days, he introduced his girlfriends to both and socialised with both. Convienently Dale Tynan has been airbrushed out of the picture by the "bad Charles brigade" but Charles was just as close to Lady Tynan whom he called Kanga as he was to Camilla. Lady Tynan later had mental health problems but did state before she died that they had been close but there was never a sexual relationship.
Not true also that Charles broke off contact with his former girlfriends, he is still friends with Lady Jane Wellesley whom he dated in the early '70s she was invited to both his weddings. Other former girlfriends are still friends besides Lady Jane, a few were invited to his wedding to Camilla.
