I told my step sisters what my dad said

So I made a post a while ago about my dad saying that if he wanted to fuck my step sister he would have been did it and how he raised her since she was 10 said she was fine and stuff…I couldn’t even call him back after that and some of y’all suggested to tell my step sisters but I really honestly thought no one would believe me at all. It sat on my mind so heavy that I just honestly didn’t look at him the same anymore and then I found out I’m having a little girl and that gave me enough will power to tell them. So I tell my oldest step sister (who isn’t the one he said this about) and she believed me. It sat on her mind for 2 days before she blew up about it in rage and said that she couldn’t take it. At the same time she told my younger step sister about it. It then sat on her mind (my dad and her are so close and she never had a dad so she really looked up to him) for 2 days and she didn’t come home…she lives with my step sister so my oldest step sister calls me saying she talked to my youngest step sister and that she isn’t ok. My little step sister does not handle things well like this so me and my oldest step sister decided to call my dad on three way and she recoded him and I conversation. After that we made a plan to reveal this to their mom. It really all hit the fan and it’s so so much more that came out along with that…. My dad had my step sisters totally against me my whole life for no reason at all…just totally messed us all up. We are waiting for her mom to get off! The worst part is her mom is very brainwashed and we are all scared that her mom will take my dads side and not do anything about it. It’s been other things her mom has never taken seriously and they were very serious situations…I feel terrible in a way because the way he justified it was saying that he has a “cut off switch” and that he never “tried” to have sex with her he just said if he wanted it to happen it could have been happened…I feel like she is honestly going to lose both her mom and the only father figure she has ever had (which I’m all for) because she doesn’t need that she is pregnant with her first child almost full term. She deserves to know how he talks about her and if her mom won’t do anything then she deserves to know how much or how little she will care about this… sorry for the long story

Update :her mom isn’t doing much about it…we were all worried called her mom she wasn’t answering so we sent someone over and she finally calls and she is having a normal Saturday…
