Because I clearly can't fuck up again or it will be continuously thrown in my face. When she was about 11 and my partner hit her on her leg, I said he would never dare do that again or he would be gone. He did it again and I told him to get out this was around a couple months later. Every time we argue she uses it to try and get to me "you let him hit me again". I know it's to make me feel bad but I said I was sorry but I thought he wouldn't. She then just goes on about it saying once is too much etc etc etc she now has gone to her room and has her music pretty loud, I told her to turn it down and she says "no" so I said well you'll need to leave if you can't respect the house. She says "I have to leave? Erm no mum, I'm sure I'll get a second chance too, maybe even more considering what I'm doing isn't illegal". It's a co stand battle. Is told her if she hates and resents me so much, why bother living with me. She says where else do I expect her to go when she is a "poor student" please tell me she is rude and obnoxious? I do what I can for her
