I (18F) live with my mom (47F) and older sister (23F). My dad passed away when I was two, so my mom raised us alone. We’re not well-off—we have debts and live in a very small house. There’s just one bedroom that all three of us share, a small living room, and a room that serves as both our kitchen and dining area. Privacy is basically nonexistent.

I have a cousin (32F) from my dad’s side who has two kids: a 13-year-old boy and a 6-year-old girl. Both kids have different fathers. She’s about to lose the place she’s been staying at temporarily, and her plan is to live in an apartment alone while leaving each of her children with their respective fathers’ families.

My mom and sister are really upset about this and want to step in—specifically, they want to take the 13-year-old boy in. He’s my cousin’s son, so technically my nephew. They see it as almost adopting him and giving him a better environment. But I’m really against it.

It’s not because I hate the kid—I don’t. I just don’t think it’s realistic. We’re already crammed in our house, and money is tight. I’m about to enter college and will need my family’s financial support, which is already limited. I’m also stressed about space and privacy—adding another person will only make things harder.

When they brought it up to me, I didn’t respond well. I just said “It’s up to you,” since I don’t contribute financially, but I think it was clear I was against it. Now my sister says I’m being rude and selfish, and I can feel the disappointment from both her and my mom. I get that they care about my nephew, but I just don’t see how this will work.

AITA for feeling this way?
