Ok let me give you a backstory first.
My future MIL & SIL do not like me. They act like they do but I can feel their dislike for me. Especially his sister. My fiancé doesn't really like his sister because of the way she's treated me in the past and is hurt with his mom about some personal issue between his dad and her. So he doesn't really care if they will be there or not. But I do because these women will be my new family and I do not want to have issues like my poor mom did with my dads fam.
I want to include them in the planning but I do NOT want his sister as a bridesmaid (I might not even have bridesmaids). Are there any suggestions that can be helpful with this touchy subject. Did any of you married brides did something special to involve your future in laws?
