We are having a wedding with less than 100 people and I already have 5 bridesmaids, while my fiancé only has 4 groomsmen (one is my brother). My parents are telling me that if I don't have my brother's wife (my SIL) in my bridal party that it will cause "irreparable damage" and that they think it's "just awful" not to include her. My mom was crying about it on the phone and now won't talk to me (that relationship is an entire other post!). I've really struggled with the decision and do want to include my SIL in the day (was going to ask her to do a reading), but my bridesmaids are my closest friends who mean the world to me. Plus it feels really weird to have 6/4 bridesmaids to groomsmen. I just don't want to cause a huge rift in my family. I should mention that I was a BM in her wedding to my brother 10 years ago. Not sure if that influences people's thoughts. Really curious how other people see this.
