So I (18F) used to live with my roommate (19F) and we were best friends before all of this. She was having problems with her old roommate so I let her move in with me. We were really close, like we’d go grocery shopping together, I’d cook most of the food and bring it to her, and we just did a lot together. She has a car and I don’t, so she would let me use it sometimes. I always asked first though, I never just took it or anything. Then she asked if I would co-own her car and split the payments with her even though everything is in her name. I told her I couldn’t because I was struggling financially and also helping pay for my mom’s medical bills, so I just didn’t have extra money like that. She said I could do payment plans with her, but I still said I couldn’t commit to that. Instead I told her I would always ask before using the car, always put gas in it, and I would pay half of any repairs or expenses if they came up. I also cooked most of the meals and helped out a lot around the apartment.
Now she’s saying I was “using her” and taking advantage of her car, and now things are really tense between us. I forgot to add she moved as we had a big argument because that really hurt me after everything Ive done for her, also she is in no financial hardship as she just got 20k from her mom for “moving money” she was planning to move out anyway but this caused the move out process to happen faster. I also paid for a new battery well half of it and always payed for gas if I drove, most of the time we would go together anyways so I rarely drove as we went everywhere together.
So AITA for not agreeing to co-own her car and thinking what I did was fair?
