I seriously doubt there really is anyone else.., and if there is.., I seriously doubt the story is exactly as she says it is.., (remember.., she likes you.., she has incentive to lie just to get you to react).., don't get disappointed.., don't start to feel the need to compete over this other guy.., don't do any of that.., (why?).., because even if there really is an other guy.., or even if there isn't.., (he doesn't exist).., that's right.., it's just YOU.., and HER.., nobody else matters in this picture.., so don't MAKE them matter..

You should take this as a good thing.., she wants to get a reaction out of you.., to gauge your interest in her.., which means.., (and tells you).., that she's interested in you..
