He had no idea what he was getting himself into. I'm sorry this was so longwinded and not really an answer to your questions. For instance, you probably want your children to be baptized into the Mormon faith when they are eight в is your fiancee okay with that.

I just wanted to let SN and AD know that, if you decide to choose this path, you are not alone.
