I know this general question has been asked before, but my brother and sister are in our wedding party and fiance's sister is not. He is fine with this, and I am fine with this. We spend time with my sibs just about every other day. My family is very close. His sister, there is no drama or anything, but we never see her. I see her maybe twice a year, and he barely sees her more than that. Apparently his mother is now guilting him, telling him that "people are concerned" about why SIL is not a bridesmaid. I don't want my fiance to be miserable about it, but I honestly don't think its any of his mom's business who's a bridesmaid. I'm not keeping SIL out because I don't like her, but my bridesmaids and I are super close and guaranteed she'd be an outsider if she were a bridesmaid also. I am just concerned that because my brother and sister are in the wedding party, that I've trapped myself into having to either ask SIL as well, or seem horribly rude?
