I read that (and anything else I could scoop up) last august. The principles are helpful, I've always had no issues with commitment (the opposite in fact) but huge issues with confrontation which slots me into this category.
Its an interesting read and did partially inform some 180s in my behaviour and conversations with w as we are now during trying to stand/db.
During my M I dont think it would have made that much difference as the one thing I absolutely know is pushing at my w gets nowhere...fast.
I already knew that standing firm works (eventually so pick those battles wisely as you'll be waiting a loooong time) but attempting to push for a specific goal when shes decided otherwise, nope, think wildcat in a corner w would just go through me first (I know she tried at least twice).
The information on responding differently could prove useful, especially if the person in question is "open" to looking at how they're truly behaving otherwise its very easy to just say nah im not doing that.
