I think his problem is that he figured out he is basically a “Nobody”. And he has been trying desperately to be a “Somebody” ever since.
Possibly. But my guess is Harry was also horribly spoiled rotten and very entitled and that was carefully hidden by the palace. All we saw were his charitable efforts, not his petulant side. He and Meghan are likely of the same mind and the fact that she’s a self absorbed shrew doesn’t weigh much with him. Maybe in time that will change. But by all accounts Harry had little or nothing to do with Meghan’s family even in the beginning. Who does that?
She walked into that marriage thinking she would change that centuries old monarchy institution as she saw fit when that never was her place to do so. She could have still lived a life of service and representation of the country but had no interest in doing so if it wasn’t entirely on her terms. Certainly not royal wife material. Hollywood self entitlement would never fit in with that kind of lifestyle.
