Gender reveal, mean step mom

Madison

OKAY everyone so I have my gender reveal coming up, my dad mentioned he was going to bring my step mom. I’ve said okay that was fine but now I’m totally thinking heck no she doesn’t deserve to be anywhere near me. My entire life she has treated me like crap for no reason, she would literally hide food from me when I was a kid I felt guilty for even eating. AND JUST RECENTLY I went to my dad for help because I needed a place to stay with my two year old because we needed a place to get away for two days and she tried to tell my dad I was using him and only come around when I need him and that I need to reap what I sow when I’ve been doing great going to school making great grades and have hardly taken any money from my dad, I only take money he offers, USUALLY, but I mean my dad makes very very good money so it’s okay that he does that. I also call my dad and talk to him every day the only reason I don’t visit is because my dad literally tells me she hates me and doesn’t want me to come over, but that day when I did come I felt like I had to get away from where I was and I wouldn’t have went unless I really needed it. SO DO YOU GUYS THINK I SHOULD SAY SHE CANT COME??? Is that being mean to my dad? I think this is very deserved I don’t want her to be there on any of my happy days because all she has done my entire life is degrade me and manipulate my dad against me!!!!!
