She seems to adopt a lot of different personas and cosplay different roles of what she thinks is expected - but without any true understanding because they are not authentic but a role she is playing.
Some of them seem to conflict with each other but the press don't call out the contradictions.
She seemed to attract Harry by being the "boho" philanthropist and Diana 2.0 - convinced him that she loved camping trips to Africa and charity work. But that seemed forgotten as soon as the marriage certificate was signed and she never visited Harry's "beloved" Sentebale projects in 7 years.
Then she was the royal "modernizer" who would whip the RF into 21st century shape through "American" workplace practices, not following dress codes, ignoring the hierarchy and establishing the Sussex Royal website to merch her products. But after 72 appearances it all got too much that they took an extended break for a couple of months and never returned.
There was a brief "we're just an ordinary couple" phase - "I'm Meghan", "just call me Harry" and we chose not to have titles for our kids. It seems to have gone out of the window with the recent title merching and "don't call me Markle - I'm Duchess Meghan Sussex"
Then there was the media mogul who would be the new Oprah by producing and appearing in a whole range of programming and podcasts and becoming a billionaire. The US companies threw $millions at them although there have been few successes. (I'm a bit disappointed that she didn't make the "Miss Havisham as a feminist icon" drama that was in pre-production a few years' ago as it sounded hilarious.)
There is also the ongoing - "we are traditional royals" u-turn with faux royal tours to Nigeria, Colombia and a speech at the UN.
The latest persona seems to be tradwife/lady of the manor - where she tries to convince us that she hosts gracious garden parties in floaty dresses while making up crap, sorry crepe packet mixes with the kids and smearing them with runny jam and pot-pourri sprinkles.
The constant reinvention must be exhausting .....
