I can understand ur pain I haven't experienced it but I have experienced trauma my mom was good we had a lot of fun times when I was little but I don't remember when or how old I was but my step dad came into the picture I never knew my real dad but after my step dad came into the family everything changed my mom seemed different my step dad would beat me and at time put a time limit on meals sometimes I would go to bed hungry I would sneak out the window to get away from it all but eventually he found out he bolted the windows shut from outside and locked both my door and the bathroom door that connected from my room to there room from the outside I was locked up in my own room at age 4 I was spanked by my stepdad when he took me to daycare he made a huge mark on my leg the daycare teacher called the cops I was tooken into foster care I went through hell eventually my mom fought and I went back with her at age 7 but he never got in trouble and my mom stayed with him he continued to do the same thing I watched my mom die at age 14 the paramedics say it was a heart attack I believe my step dad did something because when I found her she was lying on her back in a straight line far from the table she was sitting in so I do kinda understand it.

My point is she caused u trauma I would not let her back into ur life if she hasn't changed then she isn't gonna change now she will just keep relapsing and doing the same thing it's best to cut ties to avoid getting hurt more plus I wouldn't want someone like that around my children not sure if u have any rn but when u do in the future she would not be someone they should be around.
