BeingMe, I'm sorry your h isn't coming home this weekend. I know you had your heart set on sitting down and discussing the situation and divorce w/him. They do tend to have an extra sensitive radar about things and maybe he sensed this talk was coming. One never knows when you dealing w/someone in crisis.
I'm glad you went out w/a friend and vented. You needed an outlet for all of that steam that had built up. I hope you are feeling better today. I would sit quietly and wait patiently for him to return. After all, he can't stay on the run forever, he will need to return home and soon. I wouldn't ask him again when he's returning home...I would wait patiently and when he does return home, then sit down and have that conversation. You want to keep all of your cards close to the vest until he's back in the home where you can speak freely to him, eye to eye.
Until he returns, take care of yourself and do some fun things besides school work.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
