My T reacts in a similar way. The first time I told him about my SI, he asked a lot of questions, lots of details, etc. Now we don't really talk about it, even if I mention it. And when I've had suicidal ideation, we discuss it, but he definitely doesn't freak out or focus on it or anything. His way of handling it feels fine to me, and when I need to talk more about it, I do let him know.

There have been other issues, however, that I've felt I really needed him to address with me, that I didn't feel like he was giving enough attention to. It bothered me for quite a while - and finally I told him in session one day that I thought he was ignoring something that was really important to me. He totally heard me, and got it, and it really shifted the direction of my therapy in a major way.

So, if it feels important to you that this be addressed, I definitely think you should let him know. What feels scary about bringing it up with him?
