Cobra isn't interested in growing or changing... he doesn't trust Mrs. Nop because that's just how he feels about her 'attack' type style. And you can't [i]make him change how he feels.
But if he thinks he's got something from his vast store of relationship knowledge and references that you, in his certain determination thinks you should know, he's going to tell you, in any way he chooses, whether you agree or not. And he doesn't care whether you think he's does it in an authoritative or vulnerable style.
His W and His M are in a sustainable mode right now and he's read all the Art of a Warrior Relationship type books he needs to force himself in as leader. If things turn bad again, there might be enough pain involved for him (or someone) to reevaluate war plans.
But for now he chooses not to.
Sounds pretty simple to me. Jeese, Chrome, it can't get any clearer than that.... I'm sure you are implementing this plan at home as we speak.
