After skipping from page 12 to page 288 on the same subject, I realised that Grant has got one hell of an uphill battle on his hands! I'm in Australia and I have only just seen the first show!! How can this intelligent, articulate and knowlegeable man possibly hope to rise to the expectations of his wife! All he has to do is forget how to always be right, go with the flow and loosen the reigns on his life. I think he is scared witless, scared that if for one instant he lets go of the control he assumes he has, that he's going to become just another "bloke" with a wife who dresses like most wives, a house that looks like kids live and love being in and a meal that doesn't make it on to the cover of a cookbook. I so agree with all the posts I read, it would be an intolerable situation for anyone to live in, for both of them. He makes Kelly feel a failure, Kelly makes him feel unvalidated. He has great ideas (although the skintight, frenchmaid ala Daisy Duke ideas are a definate FANTASY, reality plays no part in that at all!!) about how a house SHOULD be run, how things work and an order that they work in....However, once you have children and especially babies like Grant and Kelly have, then you cannot work around a ridgid timetable, the floor you just swept and mopped so lovingly will have vomit on it or juice or something thrown on it the minute you put the mop away. You have to constantly clean, wipe up spit, poop, pee, food, drink off every flat or vertical surface, you steal the precious moments you have if one or (bless them) ALL go down for a nap, to put a load of washing on or get out of your pjs!! I know Grant reads all the posts, because he has to, control is a powerful thing and addictive and these message boards would be very hard to ignore as he must prove he's right and although he says "I'll take that into consideration", that is a very polite way of blowing you off. Its like what Dr Phil says about the word "but", it simply means ignore everything I just said, I'm now going to tell you how I really feel. 
I feel extraordinarily sorry for Grant, he can't "get it" because he doesn't know what 'it' is. It won't sink in that wives and children have an ebb and flow he can't possibly control, they are thinking feeling human beings that don't operate on schedule, that have faults, unlike his work that has to be precise and perfect otherwise it won't work. I can't imagine relaxing would be very easy for him, but expecting his wife to great him at the door in something flimsy and have a gourmet meal on the table, kids fed and in bed and the house spotless (as the 50's role models showed, oh and some of the 50's wives were closet drunks/pill poppers~Valium the pill dejour, and remember their kids became the 60's "free love" generation) is not an outrageous expectation, but for Kelly, it is unatainable. Some women can do that and probably do, but Kelly doesn't want to and that is what he has to listen to. Has Grant ever asked Kelly what she wants? Not the list of things she knows he wants her to want, but what she truly wants. I would have had Grant make a list of what he wants and expects and ticked those that were possible, crossed things that were impossible and put question marks beside all the ones that required changing her physical or cosmetic apperance. Did the children focus on his list? I'm in total agreeance that Grant focuses on himself too much, his needs, his wants, his desires and if Kelly just shapes up things will he hunkey dorey!! The children need to see their mother being pampered, being hugged and kissed when Dad comes home, they need to hear Dad tell Mum 'I love you', and 'can I help you with anything?'. If one of Grants complaints is that they don't go out often enough, then why doesn't he take the initiative and ring a babysitter (the frumpy mother-in-law maybe..lol), make the reservations buy Kelly her favourite perfume, tell her to take a long soak while he drops the kids off and spoil her rotten for the night and talk about how HER day was. 
If you read this Grant, let go of the reigns, you're pulling to tight and she is either going to become a shell of the woman you married or she is going to pack your bags. You choose, otherwise Kelly will make the decision for you. 
PS. I agree with dmmtfam, Grant makes my husband look even better than I thought he was already, he's almost a saint!! 
PPS. As for the wedding ring, it was placed on his finger with the vows to "love and cherish till death do you part", I don't recall in my vows the words "once you become the perfect wife/husband". Grant is insulting her and their marriage with his stubborness to not wear it till she 'proves herself'. Kelly should remove hers until he gets the fact that a marriage is about compromise and teamwork. Grant....You know there is no I in TEAM.
