Look at it from the outside. A man has been divorced for two years. His recent activity would be considered stalking in many states. His wife has asked him to draw back and he continually repeats that "all is not lost".
Ok. All is not lost. Turn you back to her, live your life and see if she follows. That's all you can do. You have absolutely no reason to interact with her other than the kids and the courts cut the band that gave you any excuse to do otherwise.
You are putting yourself into a legally dangerous position. You are putting your relationship with the kids in a dangerous position because you refuse to accept that you are divorced.
Certainly, you can stand for you non-marriage but you have to do it from a distance. SHE will have to come to YOU without any prompting or activity on your part. Get it? You have got to realise that if you persist in your activities it a logical possibility that you will end up in jail, have an RO pulled on you, have limited contact with your kids and on and on.
You lead, if she follows fine. She is no longer bound to you no matter how much you try to justify her behaviour.
That's my two cents. I strongly suggest that you get on with it. I'd hate to see a good man put in a position to not see his limited family again.
