I've only ever had but the purest of intentions, I feel beyond reproach about all of this beyond my presence here, yet I am aware of the ridiculous nature of that presence and the ridiculous nature of this place in which I am present now, so I would tell her exactly that, and have a good laugh at it all, I'd hope.
I do believe that not admitting that much to her upon recognizing her would be the creepy thing to do and that a later discovery would probably freak her out more, and with that much more reason.
This being said, I've never sought to meet her, I dont intend to start now or ever and there is a near zero probability that we would ever cross paths randomly, so there is no expectations to be broken, really...
The Gospels have been enough to turn this legitimate despair OP wants to discuss into what amounts to a measure of salvation, for me anyway...
