Last Christmas my fiance and I pretty well cut ties with his mother because she is emotionally abusive to him (well to everyone really). His parents divorced last year. She texts him occasionally as if nothing happend but we would really need her to apologize to us in order to have her back in our life (and that is NOT going to happen). Problem being she is still friends with his dad, and brother. She is not just going to not come to our wedding and I know that. Even without an invite Im sure we'll be seeing her. I am trying to figure out what I can do to either make sure she doesn't come to our wedding unless she puts work in to repairing her relationship with her son, or at least that she doesnt say anything really awful into a microphone on our day. There are varying degrees of terrible things she might do. There has never been an event I have seen her at where she didn't say something awful to embarrass him. What can I do? Any suggestions? Its so bad I've actually thought about hiring security. Can I do that?
