I wouldn't just start bringing up the ces letter and the problems in it. You should ask yourself if you want to have input on the way your children are raised. It's really cool to be able to connect with someone who shares all of those things with me.
I think the most important thing is to bring up the issues as questions rather than points as why she's wrong. I adore the show New Normal and one of my favorite episodes is when Bryan decides to go back to church and the Father is so cool with him. I've told her that but maybe she doesn't believe me. It takes the right personality and commitment on both sides. I hope I can forgive it someday, but even still my anger is red hot. It is nice to hear that I am not alone, and that we can do it.
Cousin the same age who just got married has known her husband 6 months. My beliefs have changed several times in my life, but not those things, so my interfaith marriage has lasted 25 years. This means that she will probably be dating others at the same time as you. What a joke for an archaeologist. Sadly, the general consensus of "convert or nope out" sounds like what will end up happening. I could never do it. He then proceeded to beat the shit out of her for a decade. It's not impossible, just painful and unlikely. The scenario where she refused to watch a possibly 'anti' documentary and wanted to watch church-sanctioned material sounds like a red flag.
I would not have wanted to be dismissed as crazy and unworthy of attention when I was still a member, because it wouldn't have been true. Mormons observe the Sabbath closely, so Sundays are for attending church meetings and focusing on their spirituality. I also felt like I could never be a good wife. If he is the right person for me, then I would wait and deal with the busy schedule in the meantime. Oh, boo hoo to me you say When you are made a promise and fall in love with a man who has a broken marriage, you begin to believe that one day you will be with him. But I'm still going to show up, even if it means I lose an hour or two of sleep. And after dating a few months we both knew we wanted to get married. I wish you the best of luck.
