I had that ex

On the day I turned around and left her, she pushed me. Down the stairs.

My leg got stuck in the railings, and got mangled, I was a scraped bruised mess when I was waiting outside for the police to arrive and help

Then she came out and she had a bloody lip, somehow.

Police actually saw through it, checked her out, told me that they understood my situation but that this was the only time they'd be able to let that pass, I needed to never see her again, or I might end up arrested.

So that's what I did. I left and never looked back
