In my sitch - I had to cut off all forms of communication (outside of anything related to the kids). It has helped tremendously, so I agree with you that going dark maybe the way to go for you.
In my cases, every time I spoke to her, every time I saw her - it was pain...pure raw pain. It would set me back for days/weeks at a time. As you begin to really detach it get's a lot better. As seeking says....this really is a process for YOU as well.
Your doing better than you think IB...much better.
God Bless, Eric
