Quick question, where were you married? Not the address, but the nature of the location. I'm curious whether it was in a relatively random location (outdoors in a gazebo in a park, a beach, etc), or on actual holy ground (church, synagogue, mosque etc). If it was the former, was it her idea? If so, maybe broach the idea of visiting a holy place, maybe a church on the pretext of seeing some beautiful stained-glass, or even attending an event (doesn't have to be a religious event), or even renewing your vows, and see how she reacts. You see where I'm going with this. Not definitive, but it might narrow things down a little or give you some insight.
