My DH won't dictate to me, but he will make suggestions as though it should be obvious to me that that is how things should be done. Then if I don't do it that way and something negative happens, he does this weird (read irritating) look on his face that is accompanied with a shoulder shrug and a palms up hand motion. Luckily it rarely happens that way!
I have everything I order shipped to work, I doubt that is workable for you, but its a thought!
p.s. a cookbook that gives recipes for your eating style/program is not another diet book, it is support materials!
