H4U,

Your wife sounds like she is acting EXACTLY how my wife acted just DAYS before she "broke" and pleaded with me to take her back, all full of remorse.

I would recommend neither asking her "what's wrong?" nor blowing her off, but rather -- if she does that again -- simply HOLD her. Strongly, For about two minutes, and then break the embrace, kiss her strongly on the forehead, and go to bed or whatever.
