I've gone out with a girl a few times. Things have gone pretty well. We were talking yesterday though, and she asked me what the worst thing I've ever done was. I gave her some lame answer because I really haven't done anything very bad. She told me that she ruined her friend's life because her friend stopped being her friend when she started dating a new guy that didn't like her. She said that made it justified and that if I ever did anything like that to her she would use every bit of information she had on me to try to ruin my life as well.
I tried to play it cool, but bells and whistles started going off in my brain when she said that, and now I'm a little panicked. I want to eliminate her from my life immediately, but the trouble is, I've divulged some information to her I don't want the whole world to know, and I'm afraid anything I do to end the relationship could upset her enough to go crazy on me.
Two questions:
a) On a scale of 1-10, how crazy do you think someone like this is?
b) How do I get rid of her without her trying to ruin my life?
