I'm married, but not "happily". While I'm not wearing my wedding ring, I am wearing a ring (sterling silver band), which I suppose some people may assume is a wedding ring.
I would say the majority of married women wear their rings every single day without fail. The only time I ever didn't wear my ring was when I went to the gym to lift weights because it bends the metal and loosens the diamonds if they're prong set.
You've got me curious. Is your wife sporting a ring on that finger? Or has a lady piqued your interest and you're trying to determine if she's married? ;-)
