I(14M)’s maths teacher (23-25F) is getting a bit too close and my parents want me to stop telling her about my life.

Hi. My teacher (I’ll call her Ms Fisher) is amazing and I love her. She’s always really nice to me and she even gave me extra help a few times. My parents asked her if I could stay after my normal class is finished a little longer and she said yes so that’s why I’m at her class for 2 hours instead of a normal hour. I never told anyone about my things before because I was afraid they’d bully me. But because Ms Fisher is so nice I decided to tell her about my life. <br><br>What I told her about, is that my dad is an alcoholic and he always hits me and my mum. Sometimes it’s so bad it leaves bruises. My mum asked him to stop hitting us, but he won’t listen. Since my dad is always drunk, my mum takes care of the house and cooks and stuff. Sometimes I help her with housework. Sometimes she’ll ask me to go to the store and buy something and when I come back my dad is hitting her but he says he’s teaching her a lesson, and he’s just showing her who’s boss. But he always listens to my mum when she tells him to stop hitting her. I think that’s because he doesn’t want me to call the police and I think he knows that my mum doesn’t want me to call the police because she wants to protect him from getting in trouble. I’m pretty sure that means he doesn’t really listen to her. Sometimes my dad will also call me a loser and some other mean names and say I don’t deserve anything. He also always calls my mum stupid even though she’s smart and I love her, and he says she shouldn’t have kids because she’s an idiot. Sometimes he’ll hit me bad and then he’ll buy me a treat and say he’s sorry but then he’ll always go back to hitting me. I try to focus on school so that I don’t have to think about it because it hurts sometimes. That’s why I need to do good in school so I can get a good job when I’m older and make lots of money and have a nice house and get treatments for my PTSD and stuff. And I’ll be able to take care of my mum because maybe she’ll leave my dad then.<br><br>I told all that to Ms Fisher the other day and she looked very concerned. Some other days I told her even more about my dad. She always listened and was really nice to me. She never told me to stop telling her things. She always said it’s okay to tell her stuff and I trust her a lot. But when my mum came to school for some reason she told her what I said and my mum got really mad. She told me not to tell her my private things again. I said Ms Fisher is nice and she listened to me and said she’ll always be there for me and stuff like that. My mum said maybe she’s not a good person and maybe she’s just pretending to be nice. I said no she’s not and she said I shouldn’t have told what’s in our house because my dad might get in trouble and she won’t tell me anything else.<br><br>I don’t know what to think. I really like Ms Fisher a lot. She’s always nice to me and she never does anything wrong. My mum never really talks to her so I don’t know why she thinks that. Do you think my mum is right? What should I do? I really want to keep telling Ms Fisher my problems. Sometimes I feel very sad because of my dad but she makes me feel better. <br><br>TL;DR: I like my teacher very much and I always feel comfortable talking to her. To her I told things I never told anyone before. It’s about my dad and how he’s mean to me and my mum. My mum doesn’t want me to talk about this to her. Do you think she’s right? What should I do?
