There’s a difference between life as a Royal and life in the Royal family, which I suppose he never picked apart and if she did vaguely understand that she worked it to her advantage.
What I mean is they are his FAMILY, and he generally seemed quite happy with his relations (or most of them anyway). Lots of cousins his age that he got on with etc. But he didn’t like Royal life, living in a goldfish bowl, having duties to perform, having his life mapped out for him. Which is quite understandable really.
Now if he had married the right woman I’m sure his family would have supported him in taking a step back. He could have retired to a Cotswold estate doing country stuff and just the minimum of Royal stuff. In short living a life not that different from his cousins Zara and Peter Phillips.
Or he could possibly have gone off to Africa like Earl Spencer did, though security and so on might have been a bit more problematic for him.
Anyway, unfortunately he married the wrong woman, who stoked his resentments, played on his deep fears of losing her like he lost his mother and isolated him from his family while convincing him they could do so much better without the RF, living in California.
Perhaps some of the counselling he supposedly had back in the day, before Meghan, could have helped him work out some of his contradictory emotions but that ship sailed a long time ago. Now we are left with a bitter husk of resentment, blaming everyone for his problems, unable to see or acknowledge where he has gone wrong and stuck in a sunk cost spiral.
