I have been using the distinction between "R" (Relationship) discussions and "P" (Partnership)discussions for a while in my own sitch. I am not sure how original it is or if I derived from something else, but I don't think I have seen it spelled out elsewhere. I just needed to keep them straight in my own mind. I recently added "B" (Boundary)discussions to my thought process when they became so apparently necesessary in my sitch.
