I married my husband 11 years ago, when he was an undergrad student. That said, I would be fully aware that Mormonism is going to compel even the best of them to do some truly horrendous stuff at times. She was expecting me to break up with her, like all previous guys she's been into have done. Would she be okay with never being married in the temple. Nothing beats a face to face talk. Even if he just has a weekend free, getting away, just teh two of us, helps so very much.
He has sacrificed parts of his career as well. My father told him it's never too late to leave whether we are married with kids or just engaged. I know my husband appreciates me looking into it because he knows I am doing it to gain an understanding into the culture he was raised in. We tried discussing his list a few times, but it only ended in arguments.
I don't think I could let that happen. It's a tricky business, but oh so worth it for the one you love. Marrying a non-Mormon is not something you do it is something that happens.
What do you guys do about this-- do you go with your spouse. Find out what your partner thinks of as non-negotiable. They nicely include all the pictures we grew up with on how the book was translated and admit that isn't how it happened. I volunteer every week, I put others before myself, etc. If you and she are sealed in a Mormon temple, your children will be can be sealed to you. You will buy expensive disability insurance, malpractice insurance, and life insurance to provide a snippet of comfort for the great, unknowable future. Your probably thinking of a sect of the Mormons, I'm sure there is one like that.
