I want 2 listen a ongoing call of any number but how?

If he still won't tell his ex about you. I bet you they still go together. He is lying to you about they relationship.

Are you sure that she is his ex. Maybe he not break up with her. Maybe she believes they are still together. If you tell her then she will leave. Most men would rather not be alone so he won't leave you at that point. Then where would he get some ass from?
