Your boyfriend is mad at you . He knows that you don't like when people raise their voice, so he tries not to.

He looks into ur eyes and says "are you going to speak?". you don't answer he puts his hands behind his head, You thought he was going to hit you. Which causes you to flinch. he knows about your past trauma so he begins trying to comfort you. His voice is apologetic "I'm so sorry " he pauses. "i didn't mean to scare you, you know i would never lay a hand on you."
