Since I have been doing it sneakily, I think revealing this will at least ruin my impression of what she thinks about me. I know that at the end of the day I am a client/patient and she is my therapist but listening to her voice and gaining insights and revealing it in front of her felt special and made me feel she would think I am 'bright'. Now, this seems like a deal breaker to me and something she might be cautious with future clients. I also feel that potentially, this may be be another reason for her to remain emotionally distant and not being spontaneous anymore in her interactions with me. Despite all my instincts telling me not to, I will tell it to her next session that I have recorded some of our sessions.
