I'm still confused, but I wouldn't worry about it. They say that people in affairs immediately lose about 30-40 IQ points, and that's been my experience as well.
I do think you would have been better off to NOT SAY ANYTHING, and just deactivate the account (kinda like a musician who makes a mistake -- "just keep on playing, they probably won't notice.")
What is it specifically that you fear? That she'll be able to find you on HERE?
