How do you tell an Ex to leave you alone after you have already told them to leave you alone? She left me for unknown reasons, but I said you leaving are you sure? She replied, "Yes, I am." My response was, "You are not coming back its over." Now she realizes she made a mistake and will not stop calling me and coming by my house. She is determined for us to "work things out", but Im not we are done. How do you get a person like this to get the point?
