No, she wasn't saintly. She had good points and bad points.
She learned how to use the Press to her advantage. She learned that she could bring publicity to good causes. She learned how to look like a million dollars. She was a good dancer and she could have lovely fun.
She learned how to upstage and undermine Charles. According to J. Dimbleby's biography of Charles, she could be quite awkward about his arrangements to see the boys at weekends, changing her mind at the last minute and so on. Obviously I don't know how often this happened.
No-one on this earth really knows what went wrong in the marriage, probably not even Charles or Diana, if she were here. I often wonder if any divorced couple can really put a date/reason down. I think it's very complicated.
In any marriage both partners make vows. Here's a thought: just because one partner fails one of the vows doesn't mean that the other must do.
She made quite a lot of having to care about her boys, as if their Granny England wouldn't have enough in the housekeeping money to keep them in food or clothes.
She put the boot in on Charles in the Bashir interview by saying that she didn't think he'd ever be king. They both behaved in a bad way towards their sons with their TV interviews. Do you behave like that if you truly 'love' your children?
Should their children forgive them? Yes.
She came out with that schmaltzy old rubbish about wanting to be the 'Queen of People's Hearts'. Pass the sick bucket, Mabel.
She wrote nice letters to people she'd met and remembered.
