I haven't even got around to asking anyone to be a bridesmaid yet, but SIL has already assumed she's going to be one and I don't know how to handle it. I don't get on with her very well for a number of reasons, mostly she keeps making snide comments about how i'm too thin and alluding to me having an eating disorder, which is completely untrue and very upsetting. Given this i'm not quite sure why she wants to be my bridesmaid, but yesterday she made it very clear that she has assumed she will be one.
Being around her is very stressful, so I don't want to increase my stress levels on the day by having her as a bridesmaid, but there's the added complication of her two daughters (aged 9 and 7), who i'd like to ask to be involved in the wedding. Any ideas of how I might tackle this? I suspect she might refuse to let her daughters be bridesmaids if she isn't one, and that's not a scenario I like the thought of either. I have tried asking my OH for advice, but he finds his sister just as difficult to deal with.
