First time poster here and on mobile, so sorry for wording and grammar.

Ok, I am sixth grade and I have a friend whom I've been friends with for three years. We have been good friends since 3rd grade. So I have some respect for her since she is a long time friend. But recently I have a change of mind. The reason for this is because she is very violent.

I was shipping two of my friends for no reason and I told both of them. One of them was chill about it but the other really wasn't and was kinda mad. I don't know why but I started to poke fun at the friend like occasionally saying the ship (I know dick move.)  That when in digital art my long time friend heard about the ship and was not happy. She was also mad that I was on hacker typer and singing Africa by toto. She said if I didn't stop she would choke me I thought of it as an empty threat and continued.

 She then proceeded to put her hand around my neck and choke me it hurt slightly not really that hard. But I was just astonished at this that she would do that. I didn't tell the teacher I don't know why but I was mad. I didn't tell her anything but I am still mad this happened a week ago. 

Am I the asshole for wanting to cut ties with her.
