AITA for defending the neighbor who flooded my apartment

I live in an apartment and the girl who lives above me is like 23 and lives alone with her kid. We dont really talk much but shes always been nice and quiet and I never had issues with her.

One night I come home from work and theres water dripping from my ceiling. Not a little bit either like full on dripping onto my couch and my floor and it had clearly been going on for a while. Turns out she left her bathtub running by accident when she was rushing to pick up her kid from daycare and it overflowed and came straight through into my place.

My couch was ruined and part of my ceiling had water damage and some of my stuff on the shelf got soaked. It wasnt a small thing. I was upset obviously but when I went upstairs to talk to her she opened the door already crying and kept saying she was so sorry and that she didnt have money to fix it and please dont report her because she cant lose this apartment.

I told her to calm down and that we would figure it out. I reported the damage to building management because I had to for insurance and they went full scorched earth on her. They wanted to charge her for all the repairs to my unit plus hers and they started the eviction process saying she violated the lease by causing property damage through negligence.

A couple weeks later the building had a hearing about it and they asked me to come give my account of what happened. I showed up and instead of just telling them the facts I also told them that she was clearly sorry and it was an honest mistake and that evicting a young mom over an accident felt extreme. I said I wasnt asking for her to be punished I just wanted my stuff covered by insurance and the ceiling fixed which was already happening.

Management ended up dropping the eviction and just gave her a warning. She cried and thanked me in the hallway after.

My partner thinks I was stupid for defending her and that I shouldve let management handle it because now if she does something else itll be my problem again. A couple of my friends said the same thing. AITA?
