Is OTHER wrong in the post ? POST : Background: I'm 18 M and I met this girl at a party of a mutual friend (18 F). Come to find out we work at the same place so get to talking and make out a few times, whatever typical party stuff. We end up talking for a couple months and spending time together on breaks and outside of work. 

Fast forward a few weeks and I'm not sure how I'm feeling about it. I tell her one night via phone call I don't want to continue talking they way we were because it seems like we're different people and want very separate things from a relationship. For example; I want a stable longer term and in her words she wants an "exciting fling". 

I knew she smoked and drank and it didn't bother me but the last couple of weeks we were talking she got really really heavily involved and that got to me because it was almost everyday. I tell her this bothers me and the result is not good. 

A few nights after I break things off I get a Snapchat from her which isn't really a big deal but it turns out to be over 80 videos of her ranting I dropped her out of nowhere and addressing details about previous relationships of mine as well as some very personal details I gave about past abuse. She said something along the lines of "no wonder that happened to you because you're a shitty person" etc., 

I haven't and have refused to start any dialogue calling her a bad person or insulting her character but she still directs social media posts towards me. I've also gotten texts from her friends calling me names and stuff. 

Tldr;

I break things off with a girl I met and in trying to be respectful towards her, I get called names and borderline harassed by her friends. I feel bad for breaking it off but don't know if IMTA.
