I am so sorry you’re in this situation, and I understand how painful and confusing it must be. A good therapist will not let you down, mess carelessly with your emotions and always have your best interests at heart. While changing the boundaries a good therapist should be mindful and careful. I do not know all the details but while reading your post I had impression it was not the case. Do you want to be hugged differently than before ? Is your disclosure about attachment the only thing that changed ? Have you told your therapist how rejected you feel after she had changed her attitude ? It is certainly woth discussing as well as your attachment. I have started my therapy during Covid so hugs have never been an option. But I had a strong attachment to my therapist, desperately wanted her to be my friend or like a sister. I remember how careful, mindful and respectful our discussions were. She allowed me to be close to her the same way as before, just now it has a new meaning for me. So far, what happened in your therapy session is not quite right in my opinion, You deserve a much safer therapy !
