I have chosen to not ask my sister to be in my wedding party. We are not especially close even though she is only a few years younger than me. We have never been close and I have a hard time even staying in contact with her, as she is not particularly pleasant to talk to. She has not at all acknowledged our engagement (she did not show up to the extended family Christmas where we announced it to most of my side of the family) and has not acknowledged it on FB after we announced it. My mother is perfectly fine with what i choose to do and in fact, has been so amazing in this process. "Do what makes you two happy, not what other people think you should do" has been her mantra every time I call and freak out about something. I still plan on inviting her and her boyfriend to the wedding, but my concern is the sideways comments that I am getting from some friends and family members. We haven't officially chosen our wedding party, as we are waiting to pick a date first, but when I have casually mentioned it to some when they have asked, the response that I get has not been positive. Am I being a mean big sister by not including her? Has anyone else came across this issue for themselves? My fiance will be having his brother as his best man. My other sibling is estranged from the entire family and will not be invited either.
