Years ago I dated a girl, seemed nice, albeit rather nerdy and shy. She talked me into dating her with the phrase "I was up all night masturbating over your picture".

We were only together for a week, but during that week she became VERY intense, very clingy, very obsessive. We didn't have sex (that was my choice) as I got some bad vibes from her. And there were some weird mind games; e.g., she'd text me asking me to call her, but when I'd call her she'd refuse to pick up, then later say she felt too shy (but wasn't too shy to tell me she was up all night masturbating over my picture).

So, after a week I decided to call it a day, I was nice to her about it, told her I liked her more as a friend, and I didn't want to lose the friendship (all bullshit, I simply detected she was wrong in the head and I didn't want her to stab me). She cried, but otherwise took it well.

Then a couple of days later, she texted me to say she'd been raped. I phoned her up, she said she was walking behind her house when a large black man jumped on her, pulled her into the bushes and raped her. I lost my shit, got really angry and wanted to take her to the Police, but she refused. I told her they can gather evidence and find him, examine CCTV cameras etc... but she still refused to go to the Police.

The next day she admitted to me that she made it up to try to win me back.
