I love my job very much and it has give me many joys, but stimultaneus many hours apart from my children, my husband and my mother when there is a need. If it is already an issue in your relationship, then it'll amplify to an extreme if you get married. I google searched for support with tears running down my face. Honestly I'd let things keep going.
You have been blessed with the equipment to make such decisions. I have feeling you stopped pursuing anyone unlikely to go for you. We learn sooooooo much from each other. If I were you, I would just nope out of it and move on. You might need to trade missionary lessons for research on her part, and we can suggest less scary resources. Being a doctor means you sacrifice for others, and your family and spouse sacrifices while standing in the shadows of your career. My Buddhist husband likes Mormons and even going to church. And, for anyone "dating" a married doctor. While it's true that Mormons are not one-dimensional and completely predictable, the odds of a successful relationship, given the OP's description of his girlfriend, are slim.
Let me tell you, it is NOT any easier. The envy of all of our friends. Religious affiliation is not the only criteria when selecting a spouse. These insane hours are wearing on me and I fear what has happened to so many I know will start to happen to us. No hard feelings, is not his fault, I said yes when he proposed based on the life wee had at that time, my fault for not doing some re search and find out how is really when you are a register or in the training programme. If you have children how will they be raised. We all wondered why should would go against such a blessing.
But those days may be gone. Based on what you have written about your GF, my opinion is that you should cut your losses and move on. My wife and her family are a good example of this. The house is perfect, with nothing out of place. Would you rather give up the prospect of being married in the temple, the assurance of children being raised in the church, and parts of Mormon culture for your boyfriend, or a great man for your beliefs. When out on a date with a Mormon guy or girl, be very decent, courteous, and well-mannered. As a non member you can not take her to the celestial kingdom to live with God and get your own worlds to populate with her. And there are questions and lessons that dual-faith couples face that zero-faith or single-faith households do not. Chances are you can't though. There is no such thing as a perfect Mormon family- regardless of whether the parents are sealed or not.
