Divorced-not done-But wondering ?

[JJAC2005]

The one thing that I am having such a hard time understanding is when you are already divorced and your ex has walked away, and is saying that she is all done with the relationship, that its over, and that you need to let go and move on, and she has no intentions of ever revisiting the relationship ever again. Your basically in a situation where there isn't anything that the 2 of you have that keeps even the slightest bit of interaction. example; we don't share any children, she refuses to let the children continue with any type of relationship that we shared over the past 7.5 years, everything has been divided up, there are no more things that have to be discussed on a personal or financial level.
There is just me, left loving someone who no longer wants anything to do with me....

All the DB'ing I've been doing and reading are fantastic tools to have and practice, but there really isn't any way to use them if the person they are intended for isn't around.

What type of advice would best serve this situation?
