I (25M) helped out a woman (19F) screaming for help and dont know how to handle it

(DV warning)
Oh and if youre not a bot please dont repost this, ideally I can delete this after and not have this crazy dude find out. Cant stop the bots tho.

So, essentially I was minutes from falling asleep. Was up cause I started a new show, gf already snoring a bit. We are both awoken by screaming of “anybody help me please!” And wailing. I had to get dressed for the super cold weather and barely wanted to put myself in that situation, considered cops.

I caught upto her. She was experiencing domestic violence. Got choked out, head smashed, face swelling, what looked like dislocated or broken wrists. Just awful. He had kicked her out without a proper jacket, and not one other frickin person went out. I iimagine in shock she could have frozen to death… blocks away from a hospital.

I finally convince her to go to the hospital but shes clearly in shock and refuses to go if I dont stay with her. I know she is likelly to go back to him no matter what but she needs casts.

I felt slightly uncomfortable because she kept asking for hugs and so I happily gave them, but after she started to be… Im not sure if it was flirting but it was a bit much, made me uncomfortable. She looked my age but informed me she was 19… I consider that like a kid compared to me (mid 20s), and so it really made me feel uncomfortable.

I was exhausted after staying up all night and tried my best to inform her the statistics about being choked. At the hospital later the shelter told me that they’re full. Nothing I can do.

She is a new neighbor. They live together. Its obvious after speaking to her she went back to him.

She wanted to talk to me (I offered support with helping her get in contact with social services and explain how she can get her disability payments that have lapsed for the last few months, or to discuss family stuff) assuming she was in a shelter but no.

She wanted me to meet the guy, who did all that. She told me so many things he did, like abusing their dog and threatening its life to control her. I have no idea how I could speak to someone like this. He’s only a teenager, and I can’t imagine someone like that being safe. I’d expect him to murder me or some shit. I only ever intended to help her get access to resources to leave, but she obviously wants me to be their friend… I don’t know how I could handle it. I’ve got my own mental health issues, last thing I need is more anxiety. Only recently started to leave the house once a day. My gf worked or she would have gone out… Im not sure why I did it but she reminds me of my younger sister.

Now I feel like attempting to help was a mistake and that I should have just called the cops
She has proof of her abuse they took pics and a statement. So atleast if she leaves before he inevitably tries to murder her she has proof for a restraining order.

But I explained first of all the danger and secondly that no matter what he says? He isn’t going to be happy about her meeting the person whose attempting to help her let alone another man. I explained how I didnt want to involved with him at all initially, now I regret even giving contact info. Would have been easier if I just went to bed…… I am glad I never let her meet my gf or come to my house, but this guy is on the same street as me. Told her about the social worker near our place but im like… unsure if even being friends would be possible when it endangers her.

Essentially, how would you handle this situation? .
