I think we may be talking apples and oranges.
He engages in pleasant past-times, yes. I didn't know he collects art and frequents art galleries, that's something. Possibly his father's interests have rubbed off. I am heartened. Even the theatre. (Thanks to Cressida, no doubt.
) So he lives a well-rounded leisurely life, okay, not narrow.
Yet, it's a bit more than that. It's his work-life that has struck me as narrow (soldiering and helicopters). I am in the age bracket of Harry and William. The one aspect that drew me to my husband was his passion for his work, his focus and ambition. He is interested in everything and is a fascinating conversationalist. However good-looking, however charismatic, I cannot imagine finding anyone attractive enough to date who does not have goals and interests and a drive to take action in the world. I don't see that in Harry. That's what I mean about him needing to mature. He seems stuck somewhere in his early 20's party persona.
Though, this leaving the military may be the brave creative leap. Might be. I just don't think any woman worth her salt would look twice at someone like Harry as a serious partner, at least not at this stage. A man with a career, with real substantial interests that bear fruit in the world, that is a man women want as a partner.
I have to disagree here a bit.
I will accept that this is what your experience has shown you, but in my experience it is very different. Aimless men do not attract partners of any worth. Such a social milieu rapidly deteriorates into ennui and an inbred aimlessness, and a plunge in social status. Most people seek to marry out of that, not into it. If someone takes their birth circumstances too much for granted they quickly get out-paced and replaced by the truly scintillating and fascinating and interesting, those with passion for something.
The truly wealthy may not have to work to sustain their lives, but most need to work to sustain their souls and spirits. They may not get paid, but they do work at something. (In this category I would not place charity work - that is to say, charity work at his level is good for the quarterly exposure for the sake of donations, but I am talking about 'work in the world', the creative spark, a life's passion).
