AITA for telling my dad’s family that he isn’t my real father?

So I’m 13 years old and my “dad” had my mom take a paternity test when I was just a few months old. When the results came back my dad found out I was not his daughter.<br><br>He took me to my grandmas house and said he had found out I was not his daughter and said my mom was cheating. When my “dad” left my mom rushed over there and explained that we were living in a small apartment and couldn’t afford to pay for a procedure for me so my “dad” was going to pretend I was his and my mom gave him a big check to do so. So I went to school the next day and everyone was calling me a bastard and said my “father” gave me away because he found out I wasn’t his. I was preparing for a hardest week of my life and I found my so called “father” in the hallway he had a smirk on his face and my mom said he was actually my real dad. When my “father” found out that my mom told the truth he was mad but as my mom was getting her divorce money from him he was okay. So he married “my mother’s best friend” who is actually my mom’s biggest enemy and had my half sister who is like my best friend. The most annoying thing is that he spends most of his time preparing for my half sister to be the next thing when I’m older but he wont train me.<br><br>I could deal with all this he is family to my half sister he is not my dad. So my half sister’s mom family just found out what actually happened 7 years ago, when I was 6 and they had no idea about it because no one knew. I told them and they would not believe me my dad got mad and said I was lying. So I pulled out the paternity test and threw it at him and said I’m sorry I wasn’t your family. He slapped me but then my mom came and said my dad was right. When my family went back to his house he took me to the park and asked me to stay away from my family because I was not part of it. I got up and walked away from him and then when my half sister was about to turn 11 my family had a party. I was walking into the back and they were preparing to talk about my half sister when she turns 13. I went to my room and cried when my mom came in and said sorry about earlier and gave me some money. So when everyone is done talking my mom said we need to go back home but as we were walking to the car my dad came up and said my half sister was going to be family and had more importance. When my “father” went to bed my mom took me to the park and was explaining to me that my step mother was a very smart person and she’s actually very smart she got my “father” to marry her and when she said she was pregnant with my half sister he was over joyed. So my step mother and my mom had a deal that my mom would get my “father” to lie about being my dad but she would get my mom my “dads” money for our whole lives. Obviously my mom agreed so she had my “father” marry her and he was happy. I asked why he couldn’t stand me my mom said my “father” thinks I’m possessed by the devil. Obviously not but we were actually both fighting to be more important and my mom wanted to keep me safe so she helped me prepare for my “dad” preparing my half sister. Obviously I was gonna preparing for both things but as my step mother is a genius we were able to get more money and my “father” wasn’t mad. Obviously my mom didn’t want my “father” to marry my step mother because she was a manipulator but my “father” said he needed someone to train me he couldn’t be a good father anymore.<br><br>So 10 months had passed since my step mother and my mom had their deal. My “father” came home drunk and when he woke up he wasn’t prepared for anything. We actually had a big family meeting last month. My “dad” family had my step mother and I family to my moms house. When my family got there we were not welcome. They said my “father” was being a horrible father to my step mother and I. So my step mother and I cried and my “father” ran off. Obviously not but my mom said my step mother and I needed to be okay family is important we are not gonna let my “father” be preparing my half sister. Obviously my family is going to be okay I can’t imagine a day without my “family” and I’m sure my “father” wont be either. I want to go family orientated. We actually have a lot of land we preparing to make a big house and my “father” is going to be living in a small apartment nearby. I’m going to be spending all my family time with my step mother and not my “father”. I want my “father” to know this is the last straw my “father” said he wont be my father he needs to pay.<br><br>So last night my “father” turned my lights off, I had a small view of him in the dark I pulled out my phone and turned on the flashlight he jumped back and said I preparing to get possessed. I threw the flashlight at him and said he needs to pay. He went back and said we preparing to give my half sister your money. I pulled out the family money and threw it at him so he cried he was poor. When my step mother family came over we preparing to view the party. When my step mother noticed I wasn’t there she said I’m not here? Someone said I wasn’t “my dads” daughter and I was a bastard. So I went to the front and said he family aren’t my family he is not my “father”. I family actually liked me we preparing to keep in touch when I move out. Now it’s been a day and my “father” preparing to be as “dad” as possible. He’s been nice to me preparing to be your dad I want my money. AITA for preparing to lie about my “dad” to my step mother and my moms family he is family to my half sister preparing to view family as my step mother and I viewed family.
