Liquid Gusto, you sound like a very compassionate person. You mention how difficult it could be traveling with your SO dietary restrictions but you also mention that you have celiac, I should think that would be stressful enough. I have a friend who has celiac and so does her daughter. My friend spends a lot time planning/preparing foods for herself and daughter, where ever they go they pretty much have to bring their own food.
In our house we all eat pretty much the same thing with slight variations.
I could not handle a spouse that ate so differently, food is too important to me. I would be concerned that it would affect my child's eating. I feel pretty strongly about starting kids on whole foods.
Life is death. We all take turns. It's sacred to eat during our turn and be eaten when our turn is over. RichMahogany.
