A, They can't face anyone from their former life right now. In a couple of years, yes, a couple, he'll be able to do so. He needs to sweep all of this mess under the rug and allow things to settle down before he will venture forth in the world he left behind. It's typical of them.
Life does go on and trust me, you are a survivor and you will be just fine. Age is just a number...it's what you do w/your life that counts.
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.
