Are Rosemary Walls’ decisions motivated by internal or external forces, or both?

Rose Mary enjoys art and dislikes rules. She frequently withdraws into her own world and is incredibly self-involved, sometimes to the point of placing her children in harm. She calls herself an "excitement addict" and is most pleased when life is an adventure.So, I would say her motivations are driven by both her own selfishness and the external forces mainly brought about by Rex. Rosemary has a family yet withdraws into what gives herself pleasure. Her sense of "excitement" comes at the expense of her kids.
