I did what you describe for the entire 1st year that I was with my current T. I'm not sure what switched. She started hinting around and would say things like "If we are going to work on stuff then I need you to feel safe enough to talk in here" She pegged my resistance, but instead of working against it -she was kinda just rode the wave with me. Then I just opened up. I also started making list and bringing them -then reading off the list. Usually those conversations led to more deep stuff.
