I recently just got engaged, and my mother and I do not have a good relationship. She openly favors my brothers and has consistently pushed me down in anyway that she can just because. I have thought long and hard about this decision and told my fiance that when I tell her I got engaged that if she is not as excited about this engagement and wedding as I am then that will be that and I will not want her at any of our wedding festivities at all. She is extremely manipulative and selfish and cares most about my two brothers and herself. She called a close relative and told them that she does not approve of how my fiance asked me and that she doesnt "even know her daughter anymore" and has reached out to that relative to complain about how she wasnt included. She has not made a point to build a relationship with me and a year ago, I told her that if she continues to choose her boys and cannot treat all three of us equally then it will greatly effect her and I's relationship and she said that was fine with her.
I have made the decision to not include her, and I have a very good support system behind me of realtives and my fiance's family, and feel confident with my decision but the big kicker is that right now, my fiance and I are looking for a home and we both still live at home. I am afraid that if I tell her she will potentially kick me out or who knows, she can be a loose canon sometimes.
I am just trying to figure out how to go about letting her know that she will not be invited to any festivities or the wedding sooner rather than later, because I really am trying to enjoy the process of the engagement and everything wedding but this has put a lot of weight on my shoulders and am not sure what to say.
Any help is extremely appreciated!
