You should have dumped her and turned her in to a counselor or her parents or something. If she's threatening herself or people you know, she's full of it and you gotta call her bluff.
I usually hear about this situation with girls being nagged by pushy boyfriends who only want to have sex. And to them, I say, "Dump him, since he doesn't respect your obvious desire to not have sex."
To you, I say the same thing. She clearly has no respect for your desire to not have sex. So dump her and be done with it. Else she'll she just be extra baggage.
It's not up to your friends to understand why you dumped her. It's up to you. Because your friends aren't involved in your relationships, right?
So you were good to dump her, regardless of what your friends think.
I'm not going to answer your poll though...because the 'point' you were trying to make...I didn't quite catch. It seemed rather vague.
