I do think his insecurities were already there, a kernel of unhappiness in that he was not free to choose his life, always the one with the relationships he couldn’t make into marriage, always the spare, but he recognised his privilege.
I think Meghan amplified it. She took those insecurities that unhappiness and nurtured it, kept pushing on it, the crying , the need for mental health support that apparently she wasn’t allowed, the desperate unhappines she said she felt and fairly immediately. From all accounts it was already growing at the time of the marriage, she’d already spoken to Oprah about an interview , and the palace said no, they even set up their foundation and trade marked tea towels and rhe like with their images, and the royals again said no, we don’t monetise it, and made the mistake of not taking it seriously enough, they thought they were being welcoming, that it would pass.
I don’t think any one really knew how bad it was until the African tour, where he was angry and rude to journalists off camera, where he used that platform to make that speech about suing the media, where Meghan cried when asked how she was.
harry had no option but to go, by this point he was married and they had Archie. What else could he do. Let her go alone? Take his kid? Live with her crying daily?
meghan thought they’d be global superstars. The cream of the a list. And now harry thinks it’s his families fault, for not recognising he had to go, to do what Meghan wanted as he was married and had a child. So for him, they let him down, and he’s angry, in his moment of need, they turned their backs, left him afloat alone in the USA with his wife, loosing his titles and funds that mattered to him, he just can’t see it any other way.
She was desperately unhappy, he was married with a kid, he had to go with her, protect her, and they said no you’re on your own.
he can’t take it out on her, so he’s taking it out on them.
