It's not that she doesn't believe you right now, but it is a bone she will never drop. I clearly stated twice that I severed things with the girl. If you want to date a Mormon guy or girl, then the best way to meet singles is by visiting the Church. I think one has to become somewhat vulnerable and broken to truly experience the best side of happy- and he will not, and can not allow that to happen.
You join the LDS Church. I told him that this wasn't working for me. He gave me a very clear answer that this was right. Fall in love, learn, make some mistakes, laugh, serve other people, reproduce, and let the whole story start again.
Don't wait for it to eventually fall apart or hope that she will change. I was shocked how much the stress, lack of sleep, etc. Hell we haven't even gone in a date yet. We all wondered why should would go against such a blessing. I have missed anniversary dinners, birthday parties l, Christmas mornings as well as day to day. I will have time to build a life with friends and activities and travel of which he will be a minor part.
I worry it will only be worse when the kids grow older. We will see what life has in stock for me and this brilliant cardiologist. I think she felt that it was important for me to understand the types of challenges in an interfaith marriage. LDSdotOrg is mostly propaganda. There was a decrease in pay but an increase in our quality of life already. Be open and talk about your ideals. It MAY be true that she will not marry him unless he converts. It sucks but ultimately what Mormonism does to people is it makes them value adherence to church more than their relationships with people. I've found it extremely difficult particularly as he does not know how to communicate.
