I am the groom to be. I have two brothers and one sister. My brother's are my best men. My fiance has one sister and one half brother. Her sister is her maid of honor. We originally agreed that my sister and her half brother would not be a bridesmaid or a groomsmen and that we would find some "other" role for them. I have never planned a wedding before and never thought deeply about any of these issues. My fiance and I had a civilized convo about it and agreed to exclude the sister and half brother. In the meantime, one of my brothers actually got married during this decisionmaking time and my sister was a bridesmaid. When my sister found out that she wouldn't be one at my wedding she was devastated. She didn't specifically want to be a bridesmaid, she just felt that the exclusion made her feel unloved by me and my bride to be and unequal to my brothers. Hearing my baby sister cry (19 yrs old) was never something I thought I was agreeing to. I suggested to my fiance that my sister become a "groomswoman" and stand on my side. For whatever reason my fiance didn't like this and wanted us to stick to excluding the half brother and little sister from the wedding party. She preferred to let her read a poem or give a toast instead. I want my sister on equal footing with my other siblings, but my fiance thinks that I am giving in to pressure from my family and that she looks like the bad guy. I told her that I would have never agreed to hurting my sister in this way and that it was my mistake for not figuring out her specific role at the beginning. Advice please.
