So my sister is getting married to an arsehole, this arsehole has kicked her and her child out of the house, has cheated on her, broken up with her multiple times, has banned me from his house for no reason, banned me from seeing my nephew and disrespects me and my younger sisters, bitches about a whole family, picks on my nephew because he is not his plus many more disgusting things. They are my sisters bridesmaids, My Sister wants me and my youngest sisters to dance with the groomsmen at her wedding she knows that we don’t know them and that we are not comfortable with this idea. Is it rude of me to refuse to dance with men I do not know. I am a rape victim, she knows that our two Younger sisters both were sexually assaulted as well. He’s the type of girl that faked sexual assault for attention! Older sister does not care that we feel uncomfortable. She told us we have to do this or we can come as guests. I told her weddings are meant to be happy places where people can enjoy the moment and if she does this it’s gonna make us hate the whole day. Is this rude of me? Should I do what she wants?
