Both Prince Charles and William saw that, and allegedly tried to warn Harry. He didn't listen.
I said at the time I thought the decision to marry was too rushed, that it didn't seem a mutually equal relationship. But an infatuated Prince was obsessed with an American actress, who was herself obsessed with notoriety and appeared to think "being royal" was some kind of game she could play.
But she didn't know enough about them, their traditions, their way of life, their history, British culture and what it means to be royal.
She didn't respect what it meant, nor was she prepared to hang around long enough to learn.

She clearly didn't heed any advice either. Tellingly, in that documentary, she talked about her friends asking her whether she knew what she was getting herself into. So it's not like she wasn't warned.
But if she felt she could power play her way out of it, then what does that say about her original motive?
It's not her I'm disappointed with the most, to be honest. Her behaviour and game plan's entirely predictable - bag a prince, court the press, get some victim clout on board with claims of people being racist or sexist or toxic against you and then pull the pin.
This whole thing, from the get go, has been about control, and when she didn't get it - as we've seen with her Dad, the media, the royal family - she walks. Cuts and runs. It's petulant and it's short sighted.
She's quoted as saying she didn't want her son growing up in "that toxic environment", but here's the rub: He's Harry's son too.
Britain is his home country, his family's there, his cousins, grandparents, he was born into a royal family, it's his birthright.
She's chosen to cut both Archie and Harry away from that, and Harry's agreed to it. More fool him.
And what might Archie have to say about all this when he's old enough? This decision she's made on his behalf?
So she gets the Duchess title (albeit with an agreement not to use it), the Prince, the royal baby, the public's sympathy, an ability to earn and control great wealth. But at what cost?

And what happens when Harry gets fed up with this new Hollywood lifestyle and being away from his family, his friends, his homeland?
What an enormous amount of pressure she's now put herself under to make this work.
I have no doubt everything we're seeing unfold has been pre-calculated, workshopped, and finessed by Meghan's "team".
The question now though is, how long will Harry be prepared to play ball on Team Meghan?
