I wanted to echo a few things that Bryant R and others mentioned, and add my own thoughts:
Are you prepared for consequences that any major changes will have for your relationship?
A tribe can mean a lot of things, what sort of relationship are you looking to fill?
I haven't seen things end well for those that jump into transitions too fast.
Paul has his Wheaton Scale, and moving from one end to the other immediately is going to appear/be pretty crazy.
To start with, I think it's important to disengage from those things that making you unhappy, and see if that changes your perspective on things.
For instance, trying a different job, and/or home is a good start. If you are feeling trapped by that economic machine, something in that cycle needs to change.
You may find that find that you don't even need to work full time, hopefully in a job you enjoy, if you live somewhere that doesn't cost much. This could leave you a lot more time to hunt/fish, and may fulfill that need for you without sacrificing everything that makes your wife happy.
A good resource for this sort of information is in the books by Jeff Yeager "The Cheapskate Next Door" and "The Cheapskates Guide to Retirement".
If that sort of life still seems unfulfilling, another possible intermediate step is Rubber Tramping. Selling everything but a van or RV and going wherever the wind blows you. Bob Wells has a Youtube channel(https://www.youtube.com/channel/UCAj7O3LCDbkIR54hAn6Zz7A
) that has lots of good information about this lifestyle, including good seasonal jobs that will allow you to live the rest of the year on couple weeks/month worth of income. He interviews lots of people with different gear setups, backgrounds, and financial plans so you may get inspired by the way that someone does things, even if they don't have their own channels. One nice thing that comes with this lifestyle is a sort of tribe. A few of Bob's videos shows a get together for a Rubber Tramp Rendezvous that ended recently in Quartzite, AZ.
Just a word of warning. I testing out going "Full Native" in my youth and got in trouble pretty fast with trespassing, taking animals out of season, etc. I'm pretty sure you'll find fulfillment with something in-between Suburban living and Hunter-gatherer.
