I'm not sure about bridesmaid etiquette but over one year before my wedding date I selected my bridesmaids. My fiance and I ended up having to cancel our wedding due to his family not being able to make it from overseas and another family member too ill to travel. When I canceled the wedding my MOH totally understood (she's my best friend so obviously) but the other bridesmaids didn't even respond to my messages for a few weeks. Needless to say, we aren't really in touch anymore and after being at my current job for over a year I've made some amazing (reliable) friends. We've set a new wedding date after our family's situations have gotten better and they are able to travel again.
How do I tell the other girls that I don't want them to be bridesmaids anymore? Is that an awful thing to do even though we don't talk?
