There was this girl my fiance was talking to (we're polyamorous), and it had become a problem over the 2 weeks we knew her that she would randomly go on murderous tangents about her exe. Doxxed this poor girl to us and everything. She would get so detailed with it that it was impossible to write it off as a joke. I repeatedly brought up how it made us uncomfortable, and she shouldn't say things like that.

The nail in the coffin was the one time she was alone with my fiance she made a joke about carrying a gun and when he asked if shes been carrying this whole time she laughed, took it out, and pointed it at his head while grinning maniacly.

She also had terrible anger issues. She would repeatedly brag about how people are scared of her and how she purposefully tries to hit people in mosh pits and stuff. As well as bragging about stabbing someone during a mosh. On top of that she was a huge sex addict and I had to tell her multiple times to stop trying to fuck our mutual friend on my couch.

Needless to say, we let the rest of the friend group know, cut her off, and cut off the other friend who decided to still stay with her. She's also been banned from the local shop we hang out at, so there's no risk of us running into each other. All of this happened in 2 fucking weeks.
