I found the book a too pessimistic and to formulaic. The author paints a fascinating picture of a general breakdown of a relationship with Initiators, etc, but leaves the reader with the impression that this is an inevitable process, like the rising sun. I realize the author has approached the subject "scientifically" (since she 'uncoupled' and is trying to make sense of it, but I feel the book may be a bit misleading to couples who may be separated or having problems. Does the author truly believe once "uncoupling' starts, all marriages are doomed for divorce? Is there truly no hope for these couples?
