Sonni, They usually stay in touch with one child. That child will be the connectiont to the family for a long time.
You've been handling thing fairly well...cut out the calls to him and allowed him to call you. What about the visits to the home? I know that you mentioned he's been a bit distanced, but is he still coming around?
What have you been doing for yourself? I hope you are taking care of yourself.
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.
