My T definitely leaves it up to me to start the discussion. Sometimes we'll end a session and she'll suggest we continue the conversation next week but it always falls on me to actually bring it up again. One time I actually asked her if she could decide what we talked about and even though she was reluctant to give in, we did an exercise that she guided me through which led to a decent discussion. Afterwords, in a lighthearted way, she told me it was going to be up to me to start the conversation in future sessions.

The amount my T talks really depends on what the topic is and how much I'm talking. For example, this last session, I sent her an email beforehand and had a hard time talking about it with her so she kind of dominated the discussion to start (which is what I wanted. I said all I had to say in the email). But as the session went on, the topic shifted a bit and I talked a majority of the second half. It really varies but I'm not always much of a talker so she is super patient with me.
