So even before you were on facebook you felt deceived and therefore betrayed--and especially since the week before you had really opened up to her.

And when you found out that her daughter was in town...T doesn't have to tell you that, but you are entitled to some sort of honest answer when you ask a question relevant to therapy. When she would not explain, it seemed logical that she was "protecting" you from knowing about her daughter. It felt insulting and condescending that T seemed to believe that she could not tell you about her daughter.
