Girls aren't socially required to be missionaries, unlike men. You are too young to deal with this. I am a nurse and have been for 10 years. But that parent-child relationship was bound to change anyways as you become an adult. His hospital "family" protected this information well, silently acquiescing and even approving his behavior. Oh, and remember LDS girls are usually good at leading guys on with potential sex to get guys to agree to what they want join the church. Dress nicely, as the girl will appreciate the effort put into looking good for her, and encourage her to do the same.
I like to think that what you said really resonated with her. If you want to date a Mormon guy or girl, then the best way to meet singles is by visiting the Church. But my choice seems to be build a life so I am not lonely all the time or stay at home waiting for him to have time for me. You must either really love blue balls, or else she is not a real deal Mormon girl. We have been married a mere 3. So marrying a doctor might be ideal for me. It's in the Mormon DNA. Her experience may or may not be typical, but it is something to consider. Also, as Joanna points out, men and women already inhabit a separate culture.
What upsets me most is that he didn't realize it was my birthday, or a big one and then that his reaction was to get defensive about his plans rather than offer an alternative for celebrating with me. Play with fire if you don't fear getting burned. Are they a functioning member in society. There will, in fact, still be churches besides our own. I am willing to add his religious observances to our worship as a couple and as a family, but should I also be willing to give up some of my participation in my own faith в for example by attending the temple or Sunday services slightly less often in order to spend more time as an entire family.
I now think that 2 is the only reasonable choice to make, even as a man в staying single my whole life в until and unless I find the woman whom I cannot live without, the woman who is a true companion to me. If He can answer prayers to help you find missing car keys, He surely can help you understand who it is that you should marry. Perhaps with a note written on the back.
