I think one has to become somewhat vulnerable and broken to truly experience the best side of happy- and he will not, and can not allow that to happen. She might not even be living according to the moral standards of the Church. I can second this, as a lifelong utahn this is why I simply have a "no mormons" policy for dating. The church really needs to tailor to more partial LDS families, imho. These girls are nervous around non-Mormons. If she can't or won't consider that the church is a lie, you need to move on because this relationship can't go anywhere. I feel as if my husband and I just live passed eachother. He had no idea what he was getting himself into.
My current atheism bothers him a little but as long as we respect each other it's fine. To others making this consideration, I would certainly suggest that you converse with your Father in Heaven about this important choice. To his defense, when we were great, we were great. Mine was in California, back in the 70s. I am really in love with him. I do not contact my gf every day unless they are online. I have to say that I am a lucky woman. Girls then struggle to reconcile degenerate popular culture with Mormon expectations.
I don't think you necessarily need to cut ties with her. I know you got a zillion replies, and I have not read them. Like, she thought that serving would remedy her of any doubts or testimony issues. I would bet this is exactly what she is thinking about you, which is why she is willing to have a relationship with you aren't a Mormon. Maybe about a year ago. This is starting to upset me though and I'm tired of waiting for change, so how should I approach the conversation. After our first kiss she lets me know she won't have sex with me because she's mormon and we'd need to be married first. He wants things to be low key for now.
Play with fire if you don't fear getting burned. That desire that they be someone other than who they were when they married you is toxic to a relationship. I think it was Spencer Kimball who counselled that before marriage you should keep your eyes wide open and then after marriage keep your eyes half shut. I deal better with inattention when he is home better than him as well.
