Currently there’s issues within my family, among my father, mother and brother. Little backstory my father was very abusive while we were growing up. I have a lot of trauma from it and ptsd that has manifested into severe anxiety. I moved out of hole at a young age due to the abuse. My father moved away about 10 years ago to another state and I have to seen him since. We’ve spoken on the phone. I keep it friendly but I have no desire for an actual relationship right now. Well he found out I’m getting married in September and he’s using my wedding as a way back to where we live to force himself into one of my siblings home to live with one of us. None of us want him to live with us because he’s abusive and narcissistic. He keeps making mentions at my wedding and how much “fun” he’s going to have because my other family members are going. I don’t know what he means by that other than he wants to start trouble for no reason at my wedding. My mother called me crying because my father was acting psychotic she said talking about forcing himself into our homes. She told me “please in-invite him”. My brother then called me saying my father disrespected his wife and called her names and my brother said if my father goes he won’t show up. Other family members already are considering not coming because he’s going. So my question is this..do I lie and tell him the wedding is canceled due to money issues, or tell him bluntly he’s not invited due to the problems he’s already causing. I’m no good at confrontation and I don’t know how to go about it. I just know my father can not be there.
