Divorced from a WAW....gut feelings

[JJAC2005]

I need a little input on this one since it appears to be a more unique situation.
I have another thread that explains in more detail the dynamics of my sitch but the bottom line is I am Divorced. (7mos)
But I thought if I placed a post on the WAW area it might get some different feedback.
My ex stunned me the entire time that we were both separated (in and out of the house for 1.5 yrs) and during the entire time (waiting period) of our D to be final, she was always being relatively nice, and wanting to be with me to still do things together and as a family….we saw each other with all the same feelings of still being a couple, even have some pretty majorly amazing date nights….and we continued to even date/see each other and do family activities until about a month after our divorce was final. **OK, I know, my bad right….I let her have her cake and eat it too….and like many others here “I am certain if I had had the information from Divorce Prevention and Divorce Busting**
Then as you might guess, BOOM, the bomb dropped, and she was ALL DONE! Basically shutting me out and building walls to protect herself from relapse and weakness. She has 2 children from a previous marriage, and even though when we were going through with the divorce, she always stressed to the children as well as me that I had been a very important part of their lives and have introduced them to so many things that they would always be able have me in their lives if they ever needed me or wanted me there. That was short lived as the first phone call I got from our 12 year old boy (basically crying that he missed me and wanted to let me know how much he still loved me) turned out to be the last contact because she couldn’t handle it, and she blocked all forms of future contact between the children and myself from that point on.
She has moved on to a new relationship, 3-4 months old now (I suspect there was a little involvement just prior to her shutting the door in Sept)

Anyway….here are my thoughts and questions?
Since I am divorced, and she has classically walked away (we have NO contact, other that the few times I have tried/asked to see the kids – and was denied)….does that/this situation play out differently in time….Do WAW ever check back, or are they gone for good? I understand “one never really knows” and each situation has its own set of chances….I’m just looking for some honest gut feeling input.
