The problem lies in I have a limited view of this as an outsider, neither from his or hers or your perspective.
These are simply feelings I get from the interactions. It does not seem likely she wants to advance the R any futher for a myriad of reasons far too complex for any of us to reason.
Now I will say this from my own experience and readings and observations, I have very rarely seen a case of where going completely dark or LRT (and I think it is overused and misused) suddenly resulted in the WAS "missing" the other person or "finding themself" or urgently wanting the other person or the R back. I think it suggests to the WAS you are ok with what they are doing and they go on with their new life.
I will also echo my thoughts I believe our (positive)behavior does not have nearly the effect on their behaviors, decisions, beliefs we would like to think. I can guarantee what effect negative behavior will have; we have all seen this.
But to the the question; what if anything can someone do to change a positive dynamic to a more positive one?
You could flat out ask. What are we doing? Where if anywhere is this headed? But we all tend to avoid direct questions we already know the answer to and do not want.
The real question is, why do you continue to interact and pursue as you do? And can you honestly live with this relationship until something "happens" to alter it?
Sorry to highjack Wes, but I hope these babbling comments are relevant to many of us.
Good night, back to bed, I have no idea why I am up at 545.
