First, you found out where she was on Vday and what she was doing...and she told you that voluntarily! Awesome baby step!
Plus, I know she's going to be noticing that today is your anniversary. So, she'll be thinking about you...
Plus, since you did so well yesterday, all of her thoughts bout you will be positive!
That's incredibly great!
So...picture this...she'll be thinking that it's your anniversary...she'll be missing you...and she'll be remembering the wonderful time y'all had as recently as yesterday.
That's enough to make her rethink the situation...and wonder why she left!!
