Question about going dark: I know this means not initiating contact, but what does it mean as far as responding to her contact? Is this totally ignoring any contact she initiates?
I believe only those who have no children could really go dark. Going dark means nothing from you. She hears nothing or sees nothing from you. Drop off the planet, kind of dark.
That's not to say you need to do it. Just explaining what it means.
I agree with what your counselor said about her moving closer to her reality and breaking up some of her fog. If you will leave her alone and let her discover that OM isn't what her fantasy thought, then you will have a better shot at her coming back. The key is to stop trying to win her.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
