I haven’t introduced myself yet, but am considering doing so when I can figure out how to put things. It may take a while.
But I did want to respond to your post and your question about your parents. I agree with those who have expressed misgivings about telling them that you no longer believe. There are several posible dangers. There are some good posibilities also, but why not “test the waters” first. You can appologise for being married in a way that they were excluded from without going so far as to say that youno longer believe that the church is what it claims. Tell them that you realize that being married in the temple excluded them, and now that you are a parent, you realize how much of a mistake that was. You could tell them that your love for them should have been a higher priority than where and by what authority you married. Or however you want to put it. This may help their feelings without saying tht all their hurt over that topic was a waste.
