My FH's good friend has a girlfriend who has never been nice to me. Until Christmas Eve it was snarky comments, an occaisonal berating, and lots of eye rolling. She's the type of girl who doesn't have any friends who are girls. this past Christmas Eve we were at a party at their house and she physically came at me (for not giving her a good enough hug goodbye) and her boyfriend had to hold her back while my FH and I ran out the door. I thought I would be the better person and take one for the team so I reluctantly told my FH that if his close friend brought her I would be fine. He recently met up with this friend and his girlfriend wants me to apologize to her for the incident on Christmas Eve. We are having a large wedding and I have family coming in from the UK and Africa and I don't want to risk having someone who is very unstable and hates me at the wedding. She is an excessive drinker and cannot hold her liquor and we are having an open bar. I'm so upset about it that I haven't had anything to eat for two days because I don't feel physically safe around this person. I don't know why I can't get over what happened but I just can't. How do I tell my FH that I don't feel safe and she isn't welcome at our wedding?
