None - or at least very few - of us know Charles, Camilla or Diana when she was alive. Nor were we in the room at the time.
So what we know is gleaned from partial or biased sources, loads of PR, endless news items & eventually our own experiences.
Diana sadly died young, & she was not allowed the everyday expectation that we may mature at our own pace, come to terms with hurts that are done to us & the consequences of the mistakes we made. Diana will always be youthful & attractive in our memories, she’ll never grow older, tired, wrinklier or menopausal.
When Diana died, her reputation was in the balance, no longer the fresh beautiful innocent well-meaning girl, she was making her own way after the divorce. She had not always behaved wisely & it was becoming known that she liked to borrow husbands. She was not always emotionally well, certainly vulnerable as the Bashir revelations show. Diana & Charles were moving towards a balanced mature shared parenthood, & that was their private business, but it didn’t sell papers so wasn’t the settled version of their marriage.
Had Diana survived, she would have built her new life, hopefully found lasting love & maybe have another child or two.
Eventually, we’d have seen Diana & Camilla present a united front to support the Queen, Charles & William because that is what the royals & aristocracy do.
