His aunt has a boyfriend, who in the city we live in is well known for bad things, including being drunk and disorderly. We invited her to the wedding as a single because we didn't want him there and she had talked to my fiancée's dad, in which he also explained that he was not invited. She took it upon herself to RSVP with a guest. oh Boy! now everyone is fighting on what to do. Technically she is a close member of the family and probably should have a guest but her boyfriend is just so bad. We have no idea how to handle this!! any suggestions...
