I(16F) told my mom (52F) that she was being inconsiderate after she said she was going to ask my father for money. My father is currently going through a difficult time because his father is ill with Parkinsons. His condition has worsened quickly and gave him at most 2 months to live. My mom is aware of this, yet while we were talking she said “im going to have to talk to your brother”, because my brother is starting uni soon and needs a car. I told her “ don’t do that right now” and when she asked why, i reminded her of my father’s circumstances. She responded by saying she has to put herself first because she always met stuff slide and mentioned the mortgage and other expenses like my brothers tuition. While I understand her concerns because she asked me for money and know shes thinking of taking care of us, i dont think right now id the appropriate time especially when hes in such a vulnerable shape. I pointed this out to her and said it was inconsiderate, especially since she knows what its like to loose parents ; she lost both of her parents. She told me,” by how you said that I understand your defending your dad but I have to out me first”. For context, I’ve never been close to my father after I found out he cheated on my mom but she also cheated and is actively doing it. They aren’t together anymore. My father lives in another country and is traveling from the city to the country side to care for his fathers old things while caring for him too. I understand my father is a horrible person for everything he’s done and I have argued with him about it. That doesn’t have to make us stoop to his level though. My mom had started crying shortly after i said it so AITA for telling my mom shes inconsiderate?
