I've been trying to re-read your entire situation. When you first separated, or actually anytime during your separation, did you try going Dark? obviously with Kids it's all most impossible to go completely Dark. I've been as Dark as possible since my wife left a month ago. My gut tells me this is the thing to do especially in the beginning. Because after all this is what she asked for, for me to leave her alone. I feel our situations a similar and I'm hoping to gain any insight I can. hopefully not at your expense.
