Is your wife a Catholic or a Traditional Catholic?
In the few cases I know of, the wife probably wouldn't have divorced and lost the faith if the husband truly had the traditional Catholic faith, and strove to make that the order of both their lives. Being raised and living in the modern world, and being so distant from other Catholics, who really, really want to be the saints they ought to be, leaves most "traditional Catholics" hardly knowing what it really means to be Catholic, and so they deceive themselves, and are shocked when their spouse leaves or their children loose the faith.
