I am very happy to read that you've finally gotten some answers and he was able to actually sit down and talk to you about his "journey". You now have a better understanding of what was going on w/him.

I hope and pray that this is the key that opens the door for more communication/interaction for both of you, as well as the children.

It definitely is a gift that has revealed a lot to you in a short span of time. You are done a great job. Keep up the good 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.
