I need some understanding 

Two weeks and holding strong...Im learning to forgive...I sent him a thank you card...to say thank you for letting me know what I do not want in a boy pretending to me a MAN!  Men take responsibility for their actions and boys blame others.  I also thanked him for FREEDOM!!

My guess is that all he wants is sex...it's a jungle dating out there, and I'd say that he's now thinking that the grass really isn't greener on the other side of the fence.  In a way, I'm sure he does miss you...you have been comfortable and familiar...now he is out in the cold.  When we're scared, we always have an overwhelming urge to run back to what's familiar, and therefore safe.  It's just in our nature, I guess.

For him, it will pass in time.  If you're tempted to take him back and see him, you too might be going through the same thing.  For you too, it will pass in time.  This readjustment period after a divorce is always difficult for all involved.  It means leaving a life that you've built together and rediscovering who you are as a person...an individual person.

My advice is to just not talk to him, unless it has anything to do with the divorce settlement or your child.  This is about self preservation...you just got out, don't let him drag you back in!  Stay strong and I wish you luck with all this!
