Would I still be just avoiding if I was thinking that I should go back to the C rather than or prior to presenting my list?
No, that's not avoidance. For some reason, you are scared to face conflict with W; going to counseling will help to sort out why you are invested in this dynamic with her and help to make a change within you. For as much as we talk about your W, the issue really is with you, that you are maintaining this state of unhappiness. Lest you feel we are all coming down on you, your reaching out here is such a healthy step ( imagine how many people suffer in silence)...you are so bright, articulate, and aware of the issues...I think C is another step in the right direction.
