I’m Not Responsible for My Sister’s Finances — I’m Not Her ATM #8

I’m 25 and work as a lawyer, but right now, I’m caught in a serious conflict with my family. My older sister (27) has never held a real job—she’s always been financially dependent on our parents. Now, they’ve decided to buy her a house to “secure her future” and asked me to co-sign her mortgage since I’m financially stable.

I refused. My mom immediately lashed out, saying, “How selfish can you be? Do you want your own sister to be homeless?” She even threw in, “You owe us!

You have a career because we paid for your education.” I was so stunned that I just hung up. Later that night, my dad called in a panic, telling me my mom was furious and that I needed to come home. When I arrived, I was shocked to see my belongings packed in boxes by the door.

My mom told me that since I didn’t consider them “family,” I had no right to keep my things in their house. She broke down crying, saying she never thought I could be so ungrateful. Despite all this, I refuse to give in.

My sister is an adult. She made her choices, and I shouldn’t be expected to fund her life just because I worked hard for mine. Am I being unreasonable?
