If you are done with her, remain firm...you can not control her actions; you can control your own. Remain firm, take a position and remain regardless of her actions. Your consistent behavior will speak clearly to her. If she feels she can "yo-yo" you for her own personal satisfaction, why not. When she's lonely she will call you, she's playing games; therefore, let her play this game alone, eventually she will tire and move on...at any rate live, love, and be Happy.
