Mormons/Lds have you heard of the Sarah Pratt story?

Sarah Pratt claimed in an interview that, while in Nauvoo, Illinois, Joseph Smith, was attracted to her and intended to make her "one of his spiritual wives" while Orson (Sarah's husband) was in England on missionary service.[8] To Smith's proposal Sarah replied, "Am I called upon to break the marriage covenant … to my lawful husband! I never will. I care not for the blessings of Jacob, and I believe in NO SUCH revelations, neither will I consent under any cirstances. I have one good husband, and that is enough for me."[9] Pratt issued an ultimatum to Smith: "Joseph, if you ever attempt any thing of the kind with me again, I will tell Mr. Pratt on his return home. Depend upon it, I will certainly do it," [10] a warning that elicited the threat from Smith, "Sister Pratt, I hope you will not expose me; if I am to suffer, all suffer; so do not expose me. … If you should tell, I will ruin your reputation, remember that."
