On Wed after a difficult session I sent him a long email about how I feel that the care between us is impacting on our relationship and becoming an obstacle to the work. I asked him if he realised that his difficulties talking about my first therapist were recurring and I said I found myself wondering whether he had addressed his feelings about that. I said that I also feel special to him and I feel we need to pay attention to that because I don't want to be hurt by shifting boundaries. Then I sent him another email obviously anxious trying to clarify everything.
Yesterday he responded:

Hi RS,

Thanks for these and your previous reflections.

Without going into a detailed response by email, I want to let you know that I am receiving what you are saying as positive and constructive and I look forward to talking about this next week.

Best wishes,
T

That was such a relief. SUCH a relief. I feel like a weight has lifted and maybe we can get back on track.
