Don’t be afraid to be stern with her…as a girl, i’m telling you…just say you have no feelings for her anymore and that’s the bottom line. leave it at that…don’t talk about in the past how good everything was etc…just hand her ALL of her stuff so she has no reason to stop by or call and be done with this. give yourself 5 minutes with her…that is it, anything longer and you won’t be getting out of there without her back in your life. good luck.
