AITAH for calling my girlfriend pathetic and breaking up with her?

I, 13M and my girlfriend, 14F had been dating for about a month and then i noticed some red flags. she'd started telling me things, such as one time her dad raped her. i immediately got concerned for her and checked in on very regulary.

About a week later she also said her mother burnt her house down, i started to get even more concerned and started checking her arms, legs, just making sure she wasn't harming herself. that same day she said she was schizophrenic so i did a bit of research and i found that schizophrenic people are very prone to depression.

i'd gotten so concerned that every hour i checked on her. After a week things calmed down and she didn't tell me much more things. i still checked on her but a little less. one day i noticed one of her friends added me on facebook, i added her back but didn't message her. a few minutes later she texts me asking if im dating my girlfriend, i said yes then immediately she started texting me asking if she told me anything such as her cousin raping her, or her mum trying to kill her. at first i wasn't gonna message back but then i got intrigued once she said she's lying to me. i messaged back saying yes actually, she has said those things.

she immediately started telling me not to trust her and that shes lying. i asked her where her proof is then she sent me screenshots of my girlfriend telling her friends and other boys similar things like this, so i messaged my girlfriend asking if she had been lying to me and she said no she was not, she then sent me photos of her holding a baby and her saying those are photos of the baby she had from her dad raping her. i looked at the photos a little closer and noticed the baby had a different hair colour and face in each photo. i also noticed one of the babys had 4 fingers and she then said it was the angle but the angle was perfectly fine. the photos were just AI. i immediately started questioning her about all these things she had told me and she said she was telling the truth so i immediately broke up with her and called her pathetic. AITAH?
