Harry's mother was a royal too. Look where it got here. And I -strongly- suspect that the reason he decided to go with his wife and leave his royal duties behind was precisely to avoid anything similar happening to her.
Are you sure that's why Harry left? It's certainly not what he said in an interview back in 2021 when he made the decision. Quoting:
**
Prince Harry has opened up about the reasons behind his historic split with the British royal family, saying the "toxic" press environment in Britain was "destroying" his mental health.
Harry, 36, spoke with late-night host and fellow Brit James Corden on Friday's show, less than a week after he and Meghan, Duchess of Sussex, informed Queen Elizabeth II that they will not be returning as working members of the British royal family.

Living a double life like that sounds pretty miserable to me, especially considering he could just do what he did instead. He seems to be doing a lot better now then how he was doing at around the time he decided to step back from royal duties.
I admit I don't know that much about Meghan, but based on how happy Harry seems these days, I think he made the right choice.
