My son and his fiancé are getting married and I like the girl very much. However, my 18 year old daughter and her don't get along. My daughter has said some Excruciating things I'm not okay with at all. It's embarrassing because it's a reflection off my parenting and my sons fiancé has felt because of her behavior we all don't like her. My daughter has an attitude behavior problem.. and my daughter in law is gorgeous, has everything going for her and there relationship is exactly how a happy married couple should be.  Going into the wedding. My youngest son is a groomsman, and my DIL 3 sisters are all bridesmaids. I don't expect her to be a bridesmaid but she's not in the wedding at all and I'm hurt. Not sure what to do.. I understand where the bride is coming from I wish this could all surpass for this day.
