After 49 years 5 months and 2 days of wedded bliss, I can assure you that women speak (and think) their own language that they are born knowing and men can't learn.
Been there done that many times. She has done the same more often. I don't go to bed and cry, I go out in shop. Some guys would be thrilled to get the silent treatment. After 45 years I don't worry about much anymore. When she is ready she will say something.
