This oddly came up between the girls my age at the hall. One elders daughter explained that if we die and come back, we couldn't marry... so after that every girl I knew went into panic mode about getting married. This was tricky for them since there weren't a lot of guys our age in our hall. I didn't want to rush into getting married just to get married, and I thought maybe the girls were mistaken or misheard, so I wrote the society. A while later I got a letter back that confirmed it.
I remember being somewhat horrified at the idea that a loving god would just take the emotions out of me so that I wouldn't feel bad... I think I'm sensible enough to understand that the marriage bond ended at death and that my husband has the right to move on. I don't need to be stripped of emotions so I can be content.
This was one of the factors in a bunch of girls getting pregnant, or getting married as soon as they turned 18... they were afraid of the end coming before finding anyone, and then never experiencing love because god would make them not want to get married.
