Why the PI? Is NC a no fault state? You may be better off getting an attorney yourself.
Contacting the OMW is a tough one. It will most likely backfire and blow up in your face.
The co-worker will also be a dead end. You are trying to use logic to change your W's behavior. You cannot use logical behavior in an illogical situation.
Have yourself prepared for the worst and hope for the best..
