Is dropping the rope clearly defined in the book? The book does asks us to let go of what is out of our control. Dropping the rope, to me at least, sounds like going cold turkey. I can see the benefit of this, but hey, aren't our WASs doing the SAME thing too? What have we seen brought so often in this forum? Cold-heartedness, pride, ever-increasing disenchantment with the spouse, and apathy.
MWD encourages us to detach, but I also get the sense (from the book) that we should do so without losing our humanity in the process.
GALs, 180s, detaching, etc. All are good, but guess what - our spouses are doing the exact same thing right now. They didn't need a book or an expert to tell them that. However, what sets DB/DRers apart from WASs (other than wanting reconciliation) is that we should be GALing, 180ing and detaching WITHOUT losing sight of what makes us human (and how we treat each other), what makes us good loveable people, what our spouses fell in love with.
