What did you need him to say when you refused to talk about it? There is usually a reason we push away from a topic. And sometimes the act of not saying anything says the most about it.

When this happened to me about one issue with T, he also did't press it. That is their training. They want us to tell them what we need. It is a skill. So I wrote an email that said something like "I did't want to talk about that, so you let me take control of the session. But I was hurting and I needed you to see that my pain was too deep for me to even face. ". There was more to it, but after I got it out, he wrote a kind reply and let me know he did see my pain and was glad I shared it with him. He still will not try to drag things out of me, but I know now that it is MY job to BRING these thing into the room with me.
