I can understand why you do not know what to do because I am confused as well. She broke up with you but did not end the relationship. Frankly, the way you described her leaving sounds like a scene in a bad movie. What drama!

I would just give her time to decide what she wanted to do next and go with the flow. Or, you can decide you don't want to be in limbo anymore and call her and tell her to either end things or come back. At least then you will know where you and she stand.
