Myself and my partner are getting married next year. I have three sisters who I plan on asking to be my bridesmaids as we are all incredibly close. My fiancé has a step sister aged 16 who i hadn’t planned on asking. There’s a 16 year age gap between us and we hardly talk. She can be very spoilt and tends to storm off in situations that don’t benefit her. As an example, if we go round for movie night and it isn’t her choice of movie, she will sulk off to her bedroom and not come down for the rest of the night. Then MIL will go after her to try and talk her down and the whole night just ends badly. But my Fiancé has said I cant not have her as bridesmaid if im having my sisters. And that I should do it ‘for him’
AIBU?
