AITA for not letting my pregnant sister move in with me after she called my apartment a "dump"?
So I (27F) live alone in a small one bedroom. It's not fancy but it's mine and I keep it clean. My sister Leah (30F) is 7 months pregnant and her boyfriend just walked out on her. She has nowhere to go and my parents live in a tiny two bedroom with no space.
Last week she called me crying and asked if she could stay with me until the baby comes. I told her I'd think about it. It would be tight but I wasn't going to say no without considering it.
Then she came over to "see the place" and just started trashing it. She said my couch was ugly, my kitchen was too small, the building was sketchy, and she didn't know how I lived like this. She literally said "I can't raise a baby in this dump."
I was hurt but I didn't say anything. Later that night she texted me like "so what do you think? can I move in next week?" and I told her no. I said she made me feel like my home wasn't good enough for her and I don't want to live with someone who disrespects my space.
She completely lost it. She called me selfish and said I'm choosing pride over my own niece. My mom called me crying saying I'm punishing Leah for being stressed and hormonal. My dad said I should be the bigger person.
Now Leah is staying with a friend temporarily but she's been posting passive aggressive stuff on Facebook about "fake family" and "people who only care about themselves."
I feel bad because she's pregnant and scared. But also she literally stood in my home and insulted everything about it. I don't think I should have to let someone live with me after they treated me like that.
AITA?
