Usually, questions are part of the initial assessment. A therapist will ask them to get acquainted with you and develop a treatment plan. After that they should decrease.

Some therapists don't like silence. Could she be asking to get you to talk?

Trusting a therapist takes time. It is a very special relationship so it is okay to feel unsure. I just started seeing one. At the moment, I have no idea what to make of her, even after 5 appointments.
