It seems she'll expect you to become Mormon. I did in college, and knew I would play 2nd fiddle to the lifelong dream. She might be everything you want, but in her eyes you are not what she has been dreaming of her whole life. Your relationship with your family will be healed, and so will you. But what does it really mean to be a patriarch, to lead your tribe.
When you said that the doctor spouse sacrifices for their patients and their family sacrifices for the doctor's career, it really described my situation. The man presides over everything. I had to tell her to stop communicating with my husband she was fired but he had urged her to "keep in touch!!. I was lucky with my TBM. Mormons are very particular about dressing. Even without temple covenants marriage is a noble and worthy institution. She is going on a mission which means she is heavily invested in performing according to the cultural expectations. If he's too tired from work to go to a party that we both wanted to go to, then I'm cool with staying in since I just enjoy his company and am happy to finally be seeing him.
Even after being in a relationship I have to take all the decision alone. I'm not saying you shouldn't pursue the relationship, but I'd only recommend marrying her if she leaves the church because she discovers it's not true. It's not that she doesn't believe you right now, but it is a bone she will never drop. I would not want my children raised Mormon which she seems intent on. Life is suddenly wonderful, and you catch yourself smiling, humming, and happy all the time. But thinking of the children I could not live with myself to do that. This is especially true when you are around others. No walking your daughter down the aisle, no giving your daughter away at the alter, nothing but you standing outside the temple waiting till it's over. I tried telling him that I know myself enough that I would not be happy in this kind of relationship. For every lesson and sermon preached about loving everyone, there are one or two lessons on avoiding outsiders because they will destroy your eternity.
It's the 1 issue in our relationship. Any advice is greatly appreciated. Initially I thought he would join the church and life would get back on the only track I knew. I, too, am the wife of a doctor dermatology resident. I knew that when I met him.
