AITA for telling my parents I wont be paying any more rent until my sister starts paying hers
Im 28, my sister is 26. I moved back into my parents granny flat behind their main house about three years ago to save for a deposit on my own place, and weve had an arrangement where I pay them 600 a month which covers part of the utilities and the wifi. My sister moved into the main house two years ago after she finished her postgrad and has been working full time since, and I always assumed she was paying something similar to me but we never actually talked about it directly.
Last night I was bringing some laundry over from my flat and could hear my parents in the kitchen on speakerphone with what sounded like a bank or a credit card company, both clearly stressed about it. I waited until they finished and offered to bump my rent up to 800 or 900 for a few months to help them get on top of things. They were really grateful, my mum nearly cried.
I asked, just as a follow up, what my sister was paying so I could work out the gap. There was a long silence and then my mum said nothing, and my dad got a look on his face I have not seen in years. He told me my sister has not paid a single cent in two years, and on top of that she just bought a brand new car that my dad has been paying the insurance on because she said she was tight that month and the next.
We had a family sit down later that evening and my sister came in defensive from the start. When my parents floated the idea of her paying 300 a month and me staying at 600, she said 100 max because she was "trying to live her life" and "saving for her own future too." I told her I had been saving for mine for three years while paying her in, and she told me to fuck off, said I was being a snitch, and stormed off to her room.
After she left I told my parents I wouldnt be paying any more rent until she starts paying hers, and that whatever she ends up paying is what Im paying too, no more. My mum got upset and said they really needed the money, and I told her thats not my problem to solve alone anymore and went back to my flat.
This morning my dad knocked on my door and told me I was being an asshole for refusing to keep paying, and when I said make my sister pay he said she wont listen to them and they cant force her. I told him thats too bad and shut the door.
AITA?
