I think t's try to stay reasonably calm so as to provide a safe environment for you. Just because she didn't show obvious signs of emotion, doesn't mean she didn't feel anything. I SH and have sui ideation, and my t remains pretty calm when talking with me . There are moments when I realise how much she cares, like when she asks me to think about how I would feel and what I would say if a close friend was in my shoes - when I look at her then, I can see the emotion in her eyes. Sometimes they just hide it well.
