My guess is that Madame is probably thinking about security and grandkids (born or yet-to-be) and such things, and wondering why you're such a fool. She might also be wondering whether you're just suffering through some sort of mid-life crisis. But, if you're successful in getting the bug to bite her, she'll think differently, and life will be wonderful. But, if she doesn't share, or come to share your dream, you'll face some really tough decisions. Personally, I think you're being entirely rational and thoughtful and deliberative and considerate, and all those other sterling qualities of a good husband, father, provider, et cetera. When ya gotta itch, aint nuthin to do but scratch it. I suspect most of us will be pulling for you, and envious as hell to boot.
