Was I wrong (abusive partner)

Over the weekend my bf and I decided to take a little getaway so we got a hotel, we went to bed around 12/1am not too sure.

We were woken up by screams coming from the room next door

*i’ve been in abusive relationships* so my partner and I woke up I was shaking and told him to call the cops.

She was screaming to get off of her and “stop” “leave me alone” we hear the guy saying “fuck you” “you just punched me”

It was SO loud, I know we weren’t the only ones to hear this.

Anyways, my bf wanted to go and knock on the door but I started panicking and told him not to go because I’d follow and I don’t know. This brought me back to my EX** partner when he’d drag me and hold me down (we were in a hotel) and I wished someone had called the cops, no one did.

All I kept saying was “call the cops” over and over again, my bf called front desk. No one answered and immediately called the cops.

At the end we hear the guy walk out, cops come knock on the door and we hear it all. She defends him and saying he didn’t hit her, she jammed her hand on the door. The cop said “someone heard you say to get off me” and she said no I was just telling him to get out because of an argument we got into”

Down played the whole thing. We ended up leaving because I didn’t want to be there, especially next door.

I told my best friend and she’s making me feel so guilty, telling me I’m a horrible person for not letting my partner go. It would be all my fault if something severe happened and now I feel awful and so depressed. My bf is telling me no, he completely understand where I’m coming from and he knows how shooken up I was. That night I didn’t sleep till 5am.

Was I wrong?

What would you have done?..
