It's one day at a time. I do understand the going dark jitters, but right now, his mind is on his internal pain and finding some relief from it. If and when he contacts you, be civil and upbeat. Treat him as you would a friend that's been out of touch for quite some time.
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.
