However, my situation is very different. If it is a good honest relationship with two well-meaning people, you need to put work into it.
She is considered "an old maid" by Mormon standards, so she may be willing to marry you--hoping you will convert datimg --but she will constantly be reminded that your marriage is inferior to the "Eternal Families" of sealed Mormons, and she will fear dying and never seeing her loved ones again.
Now I feel sadness for losing out because of fear, and a cult mindset.
She was expecting me to break up with her, like all positive effects online dating guys she's been into have done.
