I know how you feel. This week I told my T. that I feel stuck when I start talking about grieving my mom. I said I try to talk about it and then I go blank along with feeling a heaviness in my chest. I said I don't know what to say next and need help. I don't remember her saying one thing about it which seems would be very important. But, I may have kept talking and switched subjects. Sometimes she doesn't want to say anything to see where my thought process goes.

You definitely need to talk to him about the conversation (or lack thereof) between the two of you. Because, if it doesn't get better it might not be a good fit.
