It’s easy to blame Meghan’s influence but he is the one who had the privileged up bringing and continued support of his father. He should be ashamed of himself.
There's a little bit of that sentence that jumps out at me. "But he is the one who had the privileged upbringing..."
He did - a privileged and completely and utterly abnormal upbringing. Look at the charade of his parents' marriage; the media's obsession with his mother; the prurient interest in her affairs, in Camilla, not to mention the (mostly tabloid) intrusion into his own life and relationships... the media darling when he was 'Hazza' - Jack-The-Lad, sowing his wild oats. Until he had the temerity to fall in love and want to marry a woman who didn't have the right credentials to fit the defined role of a royal wife, a woman who was never going to subjugate herself to the demands or protocols of royal life.
I'm not surprised he has "unresolved issues". It would take a huge intellect and a degree of self-awareness - which he doesn't have - for him to even begin to understand the nature of his problems which are IMO firmly rooted in the whole now outdated concept of monarchy. Where one family, with all the traits and foibles of ordinary human beings, are elevated to such heights that regardless of their fallibility, a nation collectively reveres them, bows and curtseys to them.
I believe that Harry is a product of his environment, little more than that. Unfortunately, I don't think he has the necessary insight to examine himself objectively. But that doesn't mean he shouldn't try.
