I sent W a very brief email reply this morning, simply asking her to consider going to counseling with me.
I have not received a reply as yet, but I went ahead and scheduled an appointment for next Friday with a psychologist who specializes in family/marital issues involving children and divorce and separation. He's CBT oriented. I spoke briefly with him by phone, and he seems willing to help, but he has reservations about whether I can get my W to agree to come along. But we both agreed it was worth a try for the sake of the children. I intend to go to the first session alone if need be.
