The book definitely says to stop saying "I love you". Isn't the point of detaching for them to miss you? Sounds like she is missing the affection of I love you and kissing....IMHO, maybe that is what is supposed to be happening for her to wake up and see what she will lose. I am definitely no expert at this DB'ing, but that's my take.
Man, that's a tough one and an answer from a vet I'd like to see. When things started falling apart for us - and there was an OM I didn't know about - detaching and not showing affection drove her further to the OM. She had moved out of the bedroom. One of her parting shots was I could have gone to the other room and done the wild thing with her. Really?
I dunno, I think there's a point where they'll have an excuse for anything. At that point I hadn't discovered DB/DR, I wish I had as I'd have put other things into practice. I did everything wrong - the detachment would have probably had a different affect had I done the other things.
