本文探討了在情侶關係中，當一方懷疑另一方可能出軌時，所產生的賽局情境。文中利用賽局理論模型，將情境區分為動態賽局、雙方平行關係的靜態賽局，以及加入偷看手機後的情境延伸賽局。研究發現，決策的過程受到許多心理因素的影響，而其中一方若能夠瞭解另一方在各種情況下的心理成本，就有可能控制雙方相處的結果。因此，理解對方的心理狀態對於解決這類情況至關重要。在交往過程中，雙方需要考慮各種可能帶來的影響，並做出最適當的判斷。這樣的瞭解可以幫助情侶在面對懷疑和不信任時更好地處理問題，並建立更加穩固的伴侶關係，也能幫助伴侶在選擇時做出對這段感情最適當的策略以及判斷。

This article explores the dynamics that arise in romantic relationships when one partner suspects the other of potential infidelity. Using game theory models, the text categorizes these situations into dynamic games, static games with parallel relationships, and extended games following phone snooping. The research reveals that decision-making processes are influenced by various psychological factors. Understanding the psychological costs for each partner in different scenarios can potentially influence the outcome of their interactions. Hence, comprehending each other's mental states is crucial in resolving such situations. Throughout the course of the relationship, both parties need to consider the potential impacts of their actions and make the most appropriate judgments. This understanding can assist couples in better addressing issues of suspicion and mistrust, ultimately fostering a more stable partnership. Moreover, it aids partners in making the most suitable strategies and judgments for their relationship when making decisions.
