I agree with Sunrise. Unless you ask good questions, you cannot know for sure what is going on. TELL him what you think he is saying or what you perceive/THINK he is thinking about what has happened to you.

And that you are FEELING he doesn't understand or believe you.

A well-trained, ethical therapist will WANT to hear what is going on with you and your feelings. Unless you tell him, he cannot respond and help you.
