How people choose to spend money is often observable to others (e.g. based on their clothes, accessories, and social media pages), but there is a whole universe of financial decisions that are essentially unobservable (e.g. how people handle their debts, taxes, and retirement planning). We explore one context where people have an up-close-and-personal view of someone else's financial decision-making process: romantic relationships. We discuss how the endless opportunities for financial observation in romantic relationships influence a range of behaviors, including spending habits, decisions about bank account structure, and financial infidelity. Our review highlights the need for more research on the ways in which financial decisions are made, communicated, and observed within romantic relationships.

人们如何选择花钱通常是别人可以观察到的（例如，根据他们的衣服、配饰和社交媒体页面），但有一大堆财务决策基本上是不可观察的（例如，人们如何处理他们的债务、税收和退休计划）。我们探讨了一种人们对他人的财务决策过程有近距离和个人看法的背景：浪漫关系。我们讨论了恋爱关系中无穷无尽的财务观察机会如何影响一系列行为，包括消费习惯、银行账户结构决策和财务不忠。我们的审查强调需要对恋爱关系中财务决策的制定、沟通和观察方式进行更多研究。
