The married girl

Spent most of yesterday with the married girl. Its easy to pretend that her husband does not exist when it is just her and I. Of course when it gets to be after 9pm and she isn't home yet and he calls, reality starts to sink in. After she left, the plan was for her to go home, change and then go out again later that night. As soon as she left home, what did I do? I called another girl and hung out with her and her friends until married girl called me to say she was ready. When is it ever going to be enough for me? What am I trying to prove? When is it ever going to end?
