I (26) been living with my mom and nieces and nephews for 2 years now, the oldest is 17. My mom just got the oldest her first car with her tax money and ever since she’s had her car she’s been turning off her location on Life360 and lying to me. She used to tell me everything going on with her. But I told my nieces mom (my sister) she was missing school and lying about where she’s going and she told my niece I was telling her this so she messaged me “say it to my face, you’re not a kid.” I got upset and went to her and said I had told her I was worried about her and she needed to go to school and she pushed me in the chest. She’s now telling everyone she told me she was gonna push me if I didn’t get out of her face, which she never said and I was never in her face. I talked to her and told her next time we both need to talk it out and she apologized for her actions but a few days later she said to my mom that she had to push me and that she should get her car back but my mom wouldn’t let her and when she came home she was calling my mom a b for taking her car. So I went out there and told her she needs to stop talking like that bc she got her car taken away for a reason she’s not accepting the responsibility for pushing me and not following my moms rules. She then started yelling at me and she hadn’t talked to me in over a week. She thinks I don’t care about her anymore and that I should mind my own business.
So AITA for not minding my own business and getting mad at her for missing school, lying about where she’s going, and pushing me?
