Love the way you normalize the challenges of being married. The fact that she is dating an atheist non-Mormon shows pretty serious lack of conformity already. Although there are no strict rules as to who should do the asking, the Mormons are very conservative and in general, they expect guys to do the asking. It's a foolish dream I suppose. Mormons are one of the few remaining groups with healthy women. On the plus side though, after you leave the church, you'll get to spend the remainder of your days bashing it on Reddit.

Her attempts to convert you will get stronger and stronger, if you make it clear to her that you will not under any circumstances convert, she'll bounce. I would think that a comprise between you getting missionary discussions and her reading the CES letter would be even.
