Venus was raised isolated from others and her mother was her only confidant. This is something a lot of children of narcissists struggle with, wanting that relationship to heal, trying to go back and work things out, missing the whole parent/child relationship. At some points, the child often begins to accept the blame their parents laid upon them and think maybe they were the one at fault for the relationship falling apart, so they try again and again but it always goes sour. Venus needs to learn that she can't talk to her mother about anything at all, ever again, nothing for no reason. When you cut contact with a narcissist it must be complete and you must treat them as if they're already dead. Everything Venus says to her mother is going to be exaggerated and posted online so Marge can shame and humiliate her. She will always jump at the chance to humiliate her daughter until she comes crawling back begging for forgiveness.
