In the late 1990s I once raised my long-term energy concerns to my first wife. She waved them away dismissively: "Oh, I'm sure 'they' will find a cure for 'it'."
She was a "magical thinker" about many things, money as well as Peak Oil. There would always be more, whenever you needed it, somehow. Trying to save money with her was like asking her not to breathe; she just couldn't do it for long, and resented me for asking. She was great at finding sales, but her goal was to optimize how much she could buy by spending it all, not to reduce our expenses and save. About retirement planning, she once told me prophetically, "Oh, I'll never be able to afford to retire, so why bother?"
This is not the kind of person to build a long-term relationship with, even in "fat times" like we still have. I am ever so glad that relationship has ended, and I was able to find the woman I am happily married to now.
My sweetheart is on board with doing things to cut our expenses, to pay down all debts (only mortgage at this point; both cars are 11 years old), to grow more of our own food, to be more independent, etc etc.
I have to be careful in how I talk about my Peak Oil or Climate Change fears, because we have a 3-year old daughter, and thinking too much about the worst scenarios gets too up close & personal for her.
And frankly, it's nice to have a slightly more optimistic point of view around, to offset my doomer tendencies.

But so long as I couch the changes we're making in terms of saving money, doing our part to offset climate change, etc, she's 100% on board.
Also, I'm pretty sure that if I was desperately passionate about making
major changes in our life, like moving to another state, she would come along with that. So I don't want to abuse that. There are many things that she values that I also want to support, like being close to our parents (especially for our daughter to have that). And, it never hurts for the things I do, like cutting firewood on our lot, to directly benefit her -- thanks to the woodstove, it's 84 degrees for her in the livingroom as I type this on a cold morning.
