Hang in there, man. Your story is a common one, and one I’m all too familiar with.
My wife’s reaction was almost identical. We are in a good place now, but it took us almost 4 years to get here.
Here are some resources that have helped:
Natasha Helfer Parker’s book, One Family, Two Views: How to Fortify your Mixed-Faith Mormon Marriage
Jon Ogden’s book, When Mormons Doubt: A Way to Save Relationships and Seek a Quality Life
The “Mormon Mixed-Faith Marriage” Facebook group (good for both the believing and non-believing spouse)
Natasha has her own virtual counseling practice, Symmetry Solutions - we have used their services and they are really good at understanding the Mormon mixed-faith paradigm and helping both spouses approach the marriage from a healthy standpoint.
Best of luck, feel free to ask me any questions, I’m happy to discuss further.
Here’s the book: One Family: Two Views
https://www.amazon.com/One-Family-Two-Views-Mixed-Faith-ebook/dp/B07H22FKY7
There are lots of resources out there to help you out.
Look up “Marriage On A Tightrope” podcast and the associated Facebook group.
John Dehlin has a great podcast called “The Gift of the Mormon Faith Crises” that has some good tips for your situation.
These two books are also really good. I always recommend them for folks in a mixed-faith marriage situation:
