My experience with non members has been so much more meaningful and caring. Here are my thoughts as someone who grew up with a non-mormon father and as someone who married a non-mormon girl.
It is crucial to recognize that Mormonism has elements of belief, practice, and custom that work to make interfaith marriages especially difficult and inconvenient for both spouses. This is by design.
She is probably thinking she can convert you if she is with you long enough and is a good enough example. You should both sit down and have a serious conversation about what you want and what she wants and if you can both deal with the compromise.
With that being said, I have long considered myself just a tad outside super TBM since we watched Game of Thrones, drank energy drinks, and occasionally stayed in my running clothes sans garments to do yard work.
The church can be a very cruel place for single people.
