This usually works out great. Rawkcuf, maybe your comment is like your name and intended backwards, but what do you mean by differences between races. I don't know if I can do it or if I want to. The goal of dating at that age is to broaden your social circle and learn more about yourself. It has already taken him us 3 years since he got out of school and finally just matched this year.
There are two ways to go about this. That's a really sad story. Life is too short. Keep the relationship casual. But there are many people on here who truly devoutly believed in Mormonism and broke free. Trying to maintain a long-distance relationship with someone at home or attempting to date someone you meet while on mission are both distractions. Why would you behave any different now. I have been reading this blog for a while now but this is the first time I have felt I needed to add my two cents in.
Before I met my husband I had dated quite a few members and some relationships were quite serious but I never felt right about it. You will always be second place. Find someone who isn't part of a cult. They can't seem to deal with it, and shouldn't have to. Mormon girls are taught that they have a divine nature. The most important thing is an open dialogue, as you say, and utmost respect for the other person. Would she be okay with having a home that is split religiously. I'm no pushover; flexing like this just keeps our lives sane. First and most importantly, I see major trust issues in your future if you both think the other is brainwashed.
You will raise the kids by yourself, and he won't help even when he's home because he'll be too tired or feel too entitled to HIS time alone. It sucks but ultimately what Mormonism does to people is it makes them value adherence to church more than their relationships with people. I have had to compromise more often than I would have liked. She is going to be taught for the rest of her life in the church the importance of missionary work and eternal families, and Priesthood in the home. I had a lot of things going on in my personal life as well, so maybe a relationship wouldn't have worked regardless. And the longer you see her you won't be getting out of anything soon either. She doesn't want to marry you. These exclusions, dictated by doctrine, hold the potential to create wedges between you, both immediately, and in the long term.
