Step-by-step explanation:
Nora's money spending behavior has a negative impact, causing problems and conflicts in the story. Her habit of overspending and taking on debt leads to a series of events that unravel her marriage and reveal the true nature of her relationship with Torvald. For example, when Nora borrows money without her husband's knowledge to save his life, it exposes the power dynamics in their marriage and leads to a confrontation and the eventual breakdown of the relationship. Additionally, Nora's spending behavior serves as a catalyst for other characters' actions, such as Mrs. Linde's decision to reveal her true identity and Krogstad's attempts to blackmail Nora.
