Like everyone else said, she might be waiting for you to bring it up. My therapist doesn't push at all. If I end a conversation it's rare for him to bring it up again. It's rare for him to ask questions to go deeper into a topic. He relies on me to do that which means sometimes we don't get as deep as I want. Like you I get stuck wondering if he's not asking because he thinks is not important, or if he's not asking because he doesn't want to push me.
