Well, maybe you take all of this info and analysis and just tuck it into your back pocket for now. Just continue to observe and see what she keeps doing. If she has deceived you and you don't bring any of this up, she probably will believe she's gotten away with it. And human nature is such that we will try and do that again because she will feel like you've stopped looking.
