SC, going dark with kids must be very difficult. I guess I'm 'fortunate' in my sitch that W and I had no kids together.
That said, going dark saved my sanity and I hope it does for you as well. It gives you breathing room and a chance to get off the rollercoaster for a while. I wish you the best of luck with this, not for saving your M, but for saving yourself!
