I am the wife of a general surgeon in his mid 50s. I have seen love prevail over beliefs. I find there are less disappointments when I know I am completely on my own. I did in college, and knew I would play 2nd fiddle to the lifelong dream. You are a good person and she can see that. Additionally, just as corporate cultures exist, so does it exist for every family. We often have issues because of his relocation every year. And by joining I mean become just as fanatic in it as she is All her life she's been taught that she needs to be married in a Mormon temple Wife left when I came out If her family are all Traditional Believing Mormons, they will try to convert you.

Sometimes I think he is the man who shouldn't have had a family but just a career too late for that now though. If so that's a good sign. This means holding hands while walking around, or even kissing. I'll definitely talk with her about my concerns, and will be spending time with her family over the upcoming holidays so that will be a good chance to see how they treat me.

But now he is a senior doc and is called on for all the difficult stuff and can't or won't say no. Due to their religious teachings, Mormons do not smoke, drink alcohol or caffeinated "hot drinks" coffee or tea or do drugs. Mixed races, however, are NOT tied into opposing beliefs and mixed races don't try to "convert" each other.
