As I started to date and fall in love with my husband, almost everyone I knew was against it. Our children 18,13,10 have become a handful. It will definitely take patience to work through any of this with her but it sounds like she's a pretty awesome person. I chose to move on. Mormons can be pretty crazy without it.
He believes in God, but also believes that God is everywhere, and therefore does not need to be worshipped in a specific place of worship with specific prayers. I am a non-Mormon woman married to a Mormon manвwhich seems to be a less common scenario in the LDS world. I walk on egg shells as well and feel like I am merely a maid, cook, nanny, etc I work to focus on the positive but the days are ing and lonely. I have no idea if he stayed. He was lonely, as was she. I have two babies, 3 months and 3 years old and I believe they probably think my dr husband is an uncle or a distance relative bc their daddy was away for fellowship for over a yr and now away bc of his job. Really, I'm interested in this too. And for mormons, the goal is always a temple marriage and a marriage for the eternities. We are alone for many months at a time. Additionally we have no family nearby for me to rely on for help or just to combat loneliness.
It sucks but ultimately what Mormonism does to people is it makes them value adherence to church more than their relationships with people. Is it wrong not to. I also think that if marriage outside the covenant is a sin, it is not so grave as to be unforgivable. That isn't fair on you, and again will create stress and a stress point in the relationship. The church creates massive guilt and shame in children and adults usually through sex related shaming. There is much that needs to change and many hearts to educate but if we doubt some of the fundamentals then why not all of them.
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. 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. I also studied his advice for approaching and dating women.
