From what I have seen is being detached and not pursuing with limited contact (Quality over Quantity). Most of the time it is with the kids that have made this contact necessary. Not sure if I am right on this or not. In going through the "Going Dark" threads those that are out there just did not seem to work very often.
I am not saying that it is not the right appraoch as every sitch is different. Just something that I noticed over there. Not talking in over the last week has been good for me as I have been able to step back on everything. Her on the other hand I know that it will take longer than a week to think things through and stop blaming me for everything. Trying to pursue her or push her in anyway will only extend that.
Time will tell it may not be 4 weeks of NC and this doesn't matter anyhow.
