She has encouraged me to read LDS. And there's a story I'm going to look again for too. I don't think you should abandon the relationship just because she is lds. There are other issues at play here that are my husband's personal history and that he is now trying to come to grips with, and I have hope that we can put our marriage and our family back together-but the job marches on, relentlessly, and there is no time allotted for personal healing. She still lives in her hometown though. You should also be willing to date other people. Tough to say what will impact your girl most - but there's your best LDS. I am a military doctor's wife, so in addition to the hideous hours, we have deployments. The important things that keep our marriage a happy, healthy, and very loving one are the same things that keep any other marriage alive and well.
The two of you can get married in the temple and live together forever for eternity. And I don't have issues with her, hell, haven't even seen her in over 20 years, but the experience with the whole Mormon thing gave me better insight in to many things in life. My mom was a single mother with a lower than average income working full time so she understood that aspect. You are brave and good people and seem to be raising wonderful children who will be lights for everyone with whom they come in contact. Most of us were suckled on that teat too. There is no such thing as a perfect Mormon family- regardless of whether the parents are sealed or not. Mormons can be pretty crazy without it. Sure it's lonely and hard work being a "single parent". We should all remember this is a human being, and she has a brain. The reality, however, has been far from it, as the small number of wives we do have in the program seem to be busy raising their kids or not really interested in developing these relationships.
