Yes, it's very normal for them to avoid contact and disconnect things such as facebook, etc. After all, he doesn't want anyone to know what he's doing and w/whom. As I have stated many times on the forums, leave them alone. They know where you are and if he needs something, he'll contact you. When he does, be civil, don't ask personal questions or go into relationship talks. Listen to what he says and go from there.
For now, keep the focus on you and your life.
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.
