Yes, This seems a very unhelpful thing to say to a client. Like has been said before he doesn't seem to explore what is going on for you in these interactions as that is not the way he works. It would be helpful for you IMO.

I don't understand his line of how being 100% honest with you is in service of you. Telling you every little thing that bothers him or annoys him just doesn't seem like it would be very beneficial. When I think of my SO for example he gets annoyed by SOOOO many things. Some of it is stuff I do that would be helpful for me to explore but soooo much of it is his stuff that he needs to explore. His annoyances don't always reflect me. The same with you LT...what annoys your T isn't always a reflection of you. Can it be useful information to have a times. Yes of course when you appropriately at the right time.

IMO he is not empowering you by working in this way he is just making you more hypervigilent to looking at how others are reacting to you rather than looking within you. It's like you are on alert wanting for how he will respond/not respond. I do this alot with my T. She doesn't share alt of her reactions and feelings with me and drives me insane sometimes as I want her to. to be more honest and open. I can see though there are many benefits to her approach. It allows me to look at myself more and worry less about her.

We are only getting some snippets of what it is like with your T so don't see the full picture but only you know if he is more helpful to you than harmful.
