I've always felt a bit sorry for him, shovelled down the publuc school/armed services route which it was clear did not suit him. Then expected to marry the chosen one whom he did not love. Could he have said No? ... I guess so, but not easy.
He seemed to enjoy his time in the Royal Navy, mostly away from public gaze and, by accounts that I have heard, was a very good and popular officer and commanding officer; also a helicopter pilot.
I think that school was probably the wrong choice for him and as for the arranged marriage, well, I will say no more, except to say it was sad for both.
However, the Royal Family has moved on from arranged marriages mpnow.
