One of my characters is usually domineering. She confidently expresses her views as if they are the only valid ones, and thinks it's her duty to instruct others as to what to think and how to behave. When confronted by an authority figure or a group setting, her confidence evaporates and she becomes quiet and accepting of what she's told. I can imagine such a person in reality. She would be basically insecure and overcompensating for this in situations where she feels in control. In situations where she can't take charge, her confidence is insufficient and she retreats to the background. The problem is that when I come to write this character, the detains are contradictory. Sometimes she's dominant, sometimes submissive. She often insists on her own way, but can accept the what others say. I'm concerned this will come across as bad writing. Any tips?
