Before sounding mean, I have to preface this post by saying that my fiancé's parents divorced while he was young. When he was 12 years old, he made the independent decision to move out of his mom and sister's house in order to live with his dad and stepmom (a much better and safer living enviornment). He hasn't been close with his biological mother and sisters at all in the 10+ years since and barely ever sees them (once a year, maybe) as he does not agree with their life choices.
While we are inviting his four real sisters and real mother to the wedding, we would rather not allow them to have "plus one's" due to the fact that their dates or significant others have been in and out of jail and have been involved in illegal situations. I think the part that worries us most is the potential danger to our guests or to our wedding if we allow them to bring dates in addition to the drama they could cause. On top of that, my parents are paying for the entire wedding and we are limited to the number of guests.
I am really at a loss on how to handle this situation and would love some advice from someone who has dealt with this before or has experienced a similar situation. Thanks knotties!
