I'm reluctant to cover that ground again if you'll forgive me, but will say commenting about my exclusion from my child's life here has thrown up all kinds of reactions, prompting me to make some adjustments in my own thinking.
For example one kind forum member, (concerned about my welfare), suggested my daughter might be "toxic" towards me (in a way), meaning in terms of her relationship/non-relationship with me being all negative.
However, though I know my child has deliberately put out some mixed messages, and that's not a nice way to behave, when I'm in a positive mood I can still think it an achievement to have a child who is so popular, and such a high achiever, (who must work very hard, and encounter many difficulties keeping up with her professional life).
