The doctrinal and afterlife issues around a non-temple marriage are an entirely different topic, and one that I am personally much more at peace with than my questions about how one might make an interfaith marriage work in this life. I guess I can understand that because his door needs to be locked from the outside and it would be too soon in our relationship to give me a key. A grandpa sense of humor and occasional clever line from an old movie go a long way. For example, the irish, polish and the italians basically intermarried. Should either of you sisters raise your children and wonder what faith will they choose. I overheard her once saying, "being married to a doctor isn't what you think it is" and this is what I think she was referring to. Once he's out of training, though, the medical marriage is much like any other marriage and the success strategies are really all the same. So far I have been sad most of the time. So i try and be supportive with cute texts and never asking him to call me or do anything, but it is hard not to feel resentful. But my relationship with him is worth this small sacrifice.
It is very painful, considering that we have an 8-year old son. As your future self, I say this with the utmost respect and admiration: Two peas in a pod. It would put him in a position of feeling less and being looked down on. We talked about getting married early in our relationship since we had known each other forever.
I've luckily broken down my GF's defenses about the church a little bit. You join the LDS Church. Since a very young age, these girls have gazed at handsome paintings of Jesus and prophets, and learned to respect men who have spiritual confidence in their eyes. If we can say them together, great; if not. I just don't want to jump to conclusions and am trying to prepare myself for a new normal. I hate to say it, but I don't see this ending well.
I knew intern year would be brutal and I hoped residency would be a little better, and it was. I've been in a similar situation before. The religion rather, and more importantly, the church itself is integral to most mormons' identity.
