Funny, after about 6 weeks of MC post-bomb (but still mid-affair), the MC looked at H and said, "We can't make any more progress here until YOU go to IC to work on YOU. Until you resolve your own issues, there is nowhere to go in the MC"...
That is the thing about DBing. They may come back to the table to work on the M in some manner or another but until they are willing to do some hard, close introspection, the pattern will just repeat! (In my experience...)
