It sounds like you unfortunately ran into this guy at the wrong point in life. Ask her if her parents buy their underwear from a bookstore. If she won't reason with your investigation of the church, nope on out and go on your merry way. Odds are majorly against this dude. You can feel it in your bones.
How do I help sustain and grow our communication under the circumstance. So I understand how it's easy to believe nonsense when you're brainwashed from birth, and how it can be comforting to believe your life is somehow very important in the grand scale of the universe, and how you don't have to be afraid of death because you'll go on to a better place where you'll live happily ever after for eternity. I think your response is Bang on. I am more compassionate towards people who I would have stigmatized earlier. If she can accept me for who I am and what I believe, knowing that I'll never give her the eternal family she wants, then maybe we'll be ok. It's a great idea to know where you stand so that you'll be prepared when this comes up in conversation.
And the you've seen the CES letter. I am thinking about him pretty much all the time. Try to find out his schedule in detail. We have a strong relationship, so I am lucky - but lately the demands of family are becoming a bit too much to handle - and I really don't know how to 'deal' with my inlaws and 'sharing' my husband with them. On her mind, her eternal salvation depends on marrying a worthy priesthood holder.
I'm not saying you shouldn't pursue the relationship, but I'd only recommend marrying her if she leaves the church because she discovers it's not true. In her mind if you never accept the gospel you are denying her eternal exaltation as a God. Love Notes for Him. It's like talking to a wall. The first key question to as is: If the answer is yes then the relationship sounds like it's doomed. And as much as I love my boyfriend with my whole heart, I can see now that sadly maybe I might have to reconsider a life married to him. Good communication, love, support and understanding are the things you should consider.
