At the expense of sounding selfish I need to know how to proceed. I have requested that my fiancees step sister be one of my bridesmaids. Not only is she close to my fiancee but she and I are good friends. I asked her to be a part of my wedding 3 months ago, yesterday a mutual friend informed me she is 5 months pregnant . We have gone dress shopping she allowed herself to be measured and never once said anything , in fact the only thing she has said to me is that her and her boyfriend are financially unable to afford the expenses of our wedding so as a show of good faith I offered to pay for her dress that she was going to allow to be ordered in the wrong size and now everyone is telling me shes pregnant but her. I took this issue to my Matron of Honor who is a veteren wedding planner who attempted to take it up with her and instead she yelled at me regarding her privacy . I respect her privacy and can not wait for the delivery of my nephew. But I am hurt she would not tell me not only for the sake of the wedding but as a member of the famliy. I dont know what to do do i buy the dress and if so in what size or do i ask her to step down and try to find a stand in? If someone out there knows please let me know. Thank you
