Last 2 days my W has refused to wear her wedding band. Its really hard to deal with, what should I do?

I can't believe this is happening. I asked about it yesterday when I met up with her, our kids and her friend with her kids to do some post-Christmas shopping. I noticed she wasn't wearing it then. Her answer was, what's the big deal? This morning she left with D12 for church, I'm home with the sick ones, she had all her other rings on BUT that one. I asked again, and she said I don't have time for this now but you need to know I'm serious about this.

WTF???

She will be home in a few hours, what should I do? Don't say anything about it again?

I really can't believe how much something like this can hurt. Right when you start to see light, then something goofy happens.
