True, I wouldn't worry too much about your xh. He's hiding because he knows you got the papers. He's waiting until things cool down before he contacts you, i.e., he doesn't know how you took what you got in the mail...he's afraid you'll be angry at home. "Son" doesn't want any fall out from "mom".
Go on your merry way. He will contact you again very soon. It's all just a matter of timing for him.
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.
