If she claims your S wants to talk to you, you pick up the phone and you talk to HIM! Suffer through whatever VERY brief (you make it so) small talk you may have to endure with her to get your S on the line. DO NOT assume she is trying to use him to manipulate you into a convo with her; be the best dad you can be, and that includes being with your S...at all costs. Even as my D is nearing finality...being the best father is the only thing I can hang my hat on now.
