He sounds like he might be a bit depressed and could very well be in withdrawal of the ow...time will tell as to whether he has taken back up w/her or someone new. The best thing to do is to leave him alone and allow him to come to you, if and when, he wants to talk.
The best thing that you can do is focus on yourself, watch our bank statement and credit card bills. Have you noticed any changes in his appearance or spending habits? What about the internet usage?
I would suggest that you start going out a bit just to clear your head. Can you meet up w/some friends for a coffee, dinner or a movie? Sometimes it helps to get out and clear the cobwebs.
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.
