As a 30s New Yorker with similar problems, and who used to feel quite similarly (read: pretentious) about the Cats and the ADK vs the West. I think the recommendation to just get outside is the one most spot on. Yes, those areas will never be as loud as the Intermountain West, but damn if every time I get my ass on the trail I don't feel much better than if I didn't, regardless of where I am.
I would echo others on the guided trips. While I haven't done one, I submitted for a Skurka trip with the primary reason of trying to meet others with similar interests, goals, and outlook. Frankly I think what he charges is quite reasonable.
As far as convincing your spouse goes, I would echo again others who have recommended against it unless you know they like it. Find out what they enjoy, convey what you do, and then compromise, leaning towards their needs. Do everything in your power to make sure they will have a good time. Then, when you get out there and one of you is not having a good time, change the plan. Alan Dixon has a great post about this on one of the backpacking forums, I'll see if I can find it. Reading it helped me realize how I had been a bad partner previous, and how I could be much better.
And if you are successful and have a good time, practice some gratitude that you have a spouse that is willing to spend their vacation pooping and sweating in the woods with you for any amount of time. [emoji4]
Generally though, it sounds like you are relatively unwilling to compromise on what you want, which is okay...if you are willing to go alone. Going with others means relationships, and relationships usually mean compromise. Figuring out how to enjoy it alone is clearly the straightest line towards your longer itineraries, and conveniently the one you have the most control over.
Hope you get out there!
