There is a light at the end of the tunnel! You are finding out how strong you are. Don’t be afraid to talk to the police. If at the end of telling your story you don’t want anything to happen then nothing will happen. It’s your choice to make an issue of it or not but getting their feedback will most certainly help you feel better about the situation. Your situation is fucked. Your mom is fucked up. She has made bad choices for you and herself. That is not your fault. You made the best of your fucked up situation and got out. I am sooooo proud of you. You weren’t afraid to talk to others; you didn’t sit back and let yourself be a victim.
I was in your situation but didn’t stop it in time. I was 14 when my mom’s bf started with the comments and touching. I was always silent and scared stiff while he did it but then it escalated to a breaking point and I screamed no that I would not be touched by him anymore. A few years pass and he apologizes and offers to tell my mom about it because I was obviously still troubled by what had happened. (My mother had been ignoring all of my fucked up behavior/acting out. I literally had panic attacks if he was alone w/ me) He tells my mom he touched me (downplaying the sexual nature, of course) and my mother takes his side. Told me I was blowing everything out of proportion and worse that I probably baited him into doing it.
Moms don’t always make the right choice. Moms don’t always choose their daughters. My mother ended up marrying that man and tried to come crying to me when they divorced 5 years later because he was cheating on her.
You are a remarkable human being who realized that she didn’t deserve to be treated like shit. You are strong. You are beautiful. You are so fucking courageous and I am proud of you. The shelter sucks-I’m sorry about that. But it’s not as bad as losing your innocence. It is not as bad as letting that man own you. It’s not as bad as letting your mother be your fucking pimp. She’s serving you up to him on a fucking silver platter. YOU DESERVE BETTER!!! You will make better choices than she ever did. This is day one. This is the starting point. Life on your own is tough and I hope that you have other family members who may be able to help you. I was able to move in with my grandfather, couchsurf after he died, and am just now in my own place. It is the best and most liberating feeling to feel safe in your own home! You will get there! Let me know if you ever need to talk!
