My mom and sister were very happy for my fiancé and I in the begining but now that our date is coming up faster they are refusing to be any help and are actually trying to pick fights. My sister is my maid of honor and I am only having one other bridesmaid, my best friend. My sister helped out in the begining but threw a fit when she realized that I had planned some stuff without her. I hadnt even planned it with my other bridesmaid it was between me and my fiancé. It is our wedding after all. When we went dress shopping for their bridesmaid dresses she threw a fit as did my mom. They complained that none of the dresses looked good or were too expensive even though I told them that I would pay for the dress. I told my sister she could wear whatever she liked as long as the color matched my other bridesmaids dress. Now she is saying that she doesn't even want to be in the wedding and that she won't show up unless she is the only one which I think it terrible! I can't cut my friend out especially since she has been the only one supporting me, but I also don't want my sister to not be in my wedding. Oh and did I mention that my mom doesn't want to come now either? I'm just not sure how to make sure that everyone is happy. Any advice?
