Here's the thing: My aunt (mom's sister) and her husband have had a rocky relationship for as long as I can remember. Long story short, they're both fairly selfish and manipulative. I'll keep this brief and we'll just say that despite other issues, when I was 17 my mother's mother died and all the family was in town for the funeral. I woke up the day before the service to my "uncle," groping me. My mother and I confronted my aunt who immediately made excuses for this man, denying that he intended anything innapropriate. Years went by and they separated, but wouldn't divorce for monetary and religious reasons. Now she's telling the family that they're "back together." He has not been invited to any family functions since then (11 years) excluding my cousin's wedding (to which he was invited as a formality but did not attend). I do not want to invite him to our wedding. I want my aunt there, but my mother says she'll throw a fit if he's not included. I feel firmly that I'm doing the right thing, but honestly, I don't even know how my cousin invited him, when she (and our whole family) know what he did to me. After having many "discussions," with my mother, insisting that I'll explain and handle my aunt, now I'm concerned that I am making a mistake in not inviting him. My fiancee doesn't want him there either, because he makes me so nervous and uncomfortable. How can I explain things any more clearly to my mother, my aunt, and my family that I don't want this man present?
