Oh wow 1step how invalidating. I would expect more from a therapist. Even nothing would be better than that for me personally.
Then again I wonder did her text have different meanings and interpretations and of course it did because here a wink means flirt or else you are winding someone up or jeering someone. I wonder did it make her happy and smile but really this should be discussed with her. What were you hoping from her as an appropriate response to what you said? I would expect nothing from mine or a text saying I am so excited you are finally coming to the contact boundary. We will discuss this at our next session.
Every t is different, from what you have said about your y this is not something o would have anticipated from her
