My wife and I have lived in France for extended periods, so I can understand how you must feel. She attended the Paris-Sorbonne Universite, and that experience has stayed with her–in her music, in her art, in her cooking–and in most aspects of her life to this day.
We’ve found that you can live a very cosmopolitan lifestyle, even being based in San Diego. Perhaps the nature of my profession as a airline pilot, and my wife’s profession in the film industry have allowed us to connect with others of similar ideas and aspirations, to create the lives we want to live.
Perhaps, you could reach out to others who have the same depth of interests you have, and, in that, you might find a more rewarding life here, or wherever you may choose to go.
