Hypothetically: You have an ex who has contacted you out of the blue. She has done this many times before. Always what has happened is you will see her for one night and she will be gone until whenever she next decides to contact you. Do you ignore her for once or do you try and explain to her how much of a cold hearted bitch she is...which you have done before numerous times and which she seems to "forget"? Would you agree that if she really cared she would stay for more than one night? Has anyone ever been in a similar situation and had a happy outcome?
