Well, I haven't read the book, but having taken a quick look at the site and the general premise, I think I have actually been following this advice on my own.
DH controls all the finances (ok by me, I hate the stress of worrying about money, so let him do it! Plus, I don't know what is a good deal as far as GBP goes, if that makes any sense. I am still learning the ways of money on this side of the Atlantic) and I let him have his hobbies and whatever, and I don't really ever ask him to do anything. In turn, I get to sit on my butt while he does the vacuuming. Don't ask me how that worked out! I like to cook, so I do most of the cooking, and he is pretty lazy when it comes to food - like someone else said, if I wasn't around to feed him, I might come home to a skeleton!
But since I don't fancy cleaning very much, he has pretty much taken up most of those chores without me ever asking. I never thought I would be married, and especially not in a relationship that sometimes feels a bit old-fashioned, but I love it. It's like I'm in a Jane Austen novel where the women get to just read and play piano all day and not worry about "real" things other than who to marry!
I know some girls who constantly nag their guys and try to get them to change. I think I have been one of those before. In my case, I think it was often the wrong guy, because I couldn't live with certain aspects of them, but I loved other things about them, so I tried to do away with the things I didn't like. Also, having the tables turned to where I had a nagging, controlling boyfriend trying to change me or convince me to do things differently must have helped me realize how crappy it is to be that way, so now I am more relaxed in my relationship. Acceptance that the one you love will never be perfect is a very good thing!
