. I need to show her that I am not controlling. That seems to be her #1 concern . . .
WRONG.
You are no longer in the phase of addressing her concerns. The only thing you "need to show her" is a strong, confident man who refuses to live in an open marriage, who will not be played, and who is fighting for his family.
This is no longer "Plan A" time. You DID that, for 6-7 weeks. Did it cause her to end her affair?
