I asked my sister last night to be a bridesmaid in my wedding next summer. I was a bridesmaid in hers this past June, and even though we do not have a good relationship at all, I fulfilled all bridesmaid duties and was present for everything because in my mind, that's what family is supposed to do. We have no other siblings, so it is just the two of us. So when I asked her last night and her response was "Can I have some time to think about it?" I was shocked. I asked her "You need time to think about if you will be in your sister's wedding?" to which she replied yes. I was hurt, but now I am trying to figure out what to do. Has this ever happened to anyone before? How do I address the situation?
