I'm not going to blow sunshine and rainbows up your butt, because I'm just not like that. I have been successfully gluten free because I have a wonderfully supportive husband. I suppose I could have also done it alone. What I could not have done was manage this fighting him every step of the way, especially with him not being gluten free. We have a shared house, which takes absolute cooperation and consideration on the part of the gluten eater.
This sort of thing makes me fairly angry. What the hell is the problem with people who make a "in sickness and health" commitment then up and say they can't deal with it? Doesn't want to hear about it any more? Well that's just too damn bad. IMO if that is her attitude about your health, because that is what this is, it isn't food, it isn't about dinner, it is about your health, you guys have some very serious issues to work out. There are so many dinner options that are naturally gluten free that can keep you from feeling bad and no one will ever notice. Meat, potatoes and veggies, fruit and ice cream for dessert. What is wrong with things like this that she would rather ostracize you than have you be part of the family you created together?
As pointed out, you aren't symptomless. The damage from celiac doesn't happen overnight and the healing won't either. I didn't notice if anyone directed you to the newbie thread or not, but if not you need to check it out because it is possible with your wife's decided effort not to cooperate that you are missing some things you need to cover. You need to have a serious discussion about how to run your kitchen together to keep you healthy. It may help her to know that once basic rules are set up in the kitchen and everything becomes routine that it does become less a topic of discussion and more of a this is just part of life sort of thing. If she can't accept that you have a serious disease and this is how it is treated instead of taking a pill every day, you'll have some hard decisions to face.
ETA: I guess I should add that I don't want to seem all gloom and doom and crap. You just need to get your wife to be on your side. Lots of people live happy, comfortable lives with gluten eaters. I do. (That is as much sunshine as I can manage today. )
