Acting like a wimp is not going to save your marriage. Your w does not respect you because she can walk all over you and your only concern is if she will hate you.
Go PITCH BLACK!! She started this mess and you need to do something shocking and without warning, NOW! Do not contact her or respond to her in any way for awhile. Let her stew in it.
Actually it is as I said more likely that she thinks I hate her, she knows she behaved like a wretch. She expects me to hate her.
I like the idea of very minimal if not no contact but not as revenge or to show I'm no wimp. I like it because I want to stop the continual attacks we wage on each other.
