Help!!! Need opinions

Okay so all of my life me & my mom haven't gotten along, it was like she was jealous of mine and my dads relationship. We fought all the time & I moved out at 17 when I started my first job. A lot of things have happened between us and honestly she tried to kill herself in front of me. I just want your guys opinion, it's too early for my baby but I'm already nervous for when I deliver. I am super close to my aunt, she is honestly more like my mother then my own. she has taken care of me when I needed it and been the back bone in my life. Every broken heart she mended. I want it to be her and my baby's father in the delivery room with me but I don't want to break her heart and cause a lot of chaos. I just don't know what to do😓
