My take VS, is that if you really dropped the rope... he noticed... it's what I've heard, and to some degree think I've experienced...
I believe we drop the rope in stages and each time it lowers, the WAS notices...
The most recent I've seen this in my sitch is a couple weeks ago, my W indicated that sep papers were coming (which I am not likely to agree with the terms; and also coincided with getting a letter that mediation is about to begin) so I emailed my W letting her know the "good news" (as I chose to see it) and that if all goes well, we'll be able to D on schedule beginning of Nov...
My W avoided that like the plague and all last week and this weekend, she's been trying to reconnect with "pleasant" emails and phone call attempts... I have not taken the bait...
Anyhow, I think this is when we say "the WAS noticed..." and when we're supposed to keep doing what is working... as the WAS steps towards us...
