So I am the MOH in my sisters wedding which is 11 months away. I really can not stand her fiance, and am really having a hard time supporting this wedding (especially knowing she plans to have kids with him right away!) He is a self absorbed a** and he is slowly pulling her away from her friends and family. Out of our mutual friends, none of the girls husbands/boyfriends can stand him and hate when she brings him along. Even one of our close friends told me she doesn't want to go to to the wedding. Me and my sister were always very close (she was my MOH for my wedding, which her fiance caused issues at and ended up being taken away by the cops). I want her to be happy and I want to be there to help her like she helped me, but it is really hard when I don't support their marriage. Should I just stick it out for her, even if I see this being a miserable marriage in the future? Or should I stand my ground and express my feelings?
