I thought I would post here as well, since I started this from this post.
I'll back off now, regarding the approach that is being promoted in this forum. I do think the method by which some of the members are getting to an emotional state where they are prepared to use this method, it still is a valid method according to MWD.
The After the Last Resort Technique does in fact indicate that a BP who is at the end of the rope and still does not want to give an Ultimatum, but is prepared for the M to end, indicate to the AP that they are (paraphrased) done and moving on.
The BP would then go completely NC, unless there are kids, and then the only comm would be specifically about the kids.
Until such time the AP wants to engage and the BP would stand firm and only engage once the AP figured out that there will be no R until the OP is gone.
So as I mention, it's a valid technique and while I may not execute the technique quite the way some approach it here, if a BP wants to go this route, fair enough.
So either it will work, or it won't. Where it did not work for me is, my W never did express interest in engaging me when I went this route, except for the kids. So for all intents and purposes, my only option IS to move on.
