Fuck, this is almost exactly what the girl I was recently dating (had been dating for about a year) was doing to me. Except that the 'quality' time I spent with her just kept getting nastier and nastier. Eventually she started talking about how much she wanted to screw that and that guy, and tried to arrange a date with one of my best friends. Not dating her anymore after that

It feels like she's playing war games or something. And she still hasn't stopped. She is manipulative as hell, but I also don't think she's entirely aware of what she is doing. (if she was, I think she would be a lot nastier) I try to ignore her as best as I can though, and filter out the more bizarre things she says on those rare occasions when I actually HAVE to listen to her. I just can't be bothered to give a fuck about her anymore. She's burned her bridges as far as I'm concerned. I'm worth so much more.
Anyways, thanks for making this post. You made me see a pattern in all the shit she's pulled on me, and now it'll hopefully be easier for me to recognize it if someone tries to do something similar again.
