I'm getting married in september. One of my best friends is in my wedding and so is her daughter, her husband is abusive. I've seen him beat her right in front of me and heard it from the next room over. I still want her and her daughter in my life but I don't want to be around him. She wants to know if he is invited to the wedding. I asked if she would be offended if I said no and she said she would be. I'm not sure what to do here.
