SteveS - Great summary post, I need to bookmark this.
One thing I am trying out this weekend is joining a men's group. It is not a NMMNG group specifically, but basically one with very similar goals that our MC (of all people) privately recommended to me.
NMMNG recovery is a lot of work and I imagine will take months if not years. The small steps of progress I see in myself (such as saying "no" without fear of conflict erupting) are invigorating.
