I honestly don't know Sheryl,
My children were older so when he would run away from home, he would contact them direct and he made plans with them. I do know that I never got this one right, because I just couldn't, I was always wrong.
If I had a do over (really not wishing for one here) but I would put on an emmy award worthy performance. Total detachment !!!!!!!!!!!!!! Phone call, I would just say, let me check the calender and see if that is a good time. If he just dropped by, or came home, I would tell him that I was just on my way out. Would act like his disappearance meant nothing at all to me.
Stay around, you might get better answers from other people that were/are in this situation.
For now I will
while I also await answers for this situation. I never knew how to deal with "crazy".
