My W just left the house and got extremely angry with me. We had been getting along fine in each other's company but she just asked for some cash to go and I gave her a weird look. She took it the wrong way and stormed out.
Anger is better than indifference. Do not fear her anger. Do not supplicate. Do not get baited into an argument. You are the rock. Any emotional response from you will help her "justify" her actions.
THE FIRST ONE TO REACT EMOTIONALLY LOSSES.
The day after and she is clearly still anger if not hostile. I'm putting on a good face and acting as if everything is fine. She won't look at me or speak to me. All of this over nothing but I'm acting as if.
