My fiance has an older sister that is one year older than him ( she is about to be 25), and from the day I met her she has been nothing but rude to me. His sister is in an on and off relationship with the father of her child, and they are constantly fighting ( verbally and physically) and they are constantly breaking up. From the day I met her she was sooo rude to me, and she loves to write hateful things on FB about the fiance and I. My fiance and his sister don't really have a relationship( even though she lives 20 mins away), because of her rude attitude.
We decided out of kindness to involve her in the wedding by making her a bridesmaid, and she complained about EVERYTHING, and then she told us to go find someone else because she doesn't want to be a part of the wedding. Her daughter was supposed to be a flower girl and she pulled her out of the wedding as well. We try to include her, but she doesn't
