5 Shocking Truths About Whether Jeremiah Cheats On Belly In The Summer I Turned Pretty

The question of whether Jeremiah Fisher cheats on Belly Conklin is arguably the most fiercely debated topic in The Summer I Turned Pretty fandom, and as of December 19, 2025, the answer has become significantly more complex—and controversial—due to plot changes in the TV adaptation. The simple truth is that what happens between Jeremiah and Belly in the book, We'll Always Have Summer, is a gray area of betrayal, but the TV show’s interpretation of the incident has escalated the situation into a full-blown cheating scandal, creating a massive rift that directly leads to the end of their relationship.

The core of the issue revolves around a pivotal moment during their relationship in college, often referred to as "The Cabo Incident." While the original novel by Jenny Han frames the event as Jeremiah sleeping with someone else during a temporary, unspoken "break," the narrative presented in the latest season of the Amazon Prime Video series has been heavily adjusted to heighten the drama and, for many fans, solidify the action as an unfaithful act. This shift is crucial for understanding the ultimate trajectory of Belly's love triangle with the Fisher brothers, Jeremiah (Gavin Casalegno) and Conrad (Christopher Briney).

The Definitive Breakdown: Book Betrayal vs. Show Cheating

To understand the true nature of Jeremiah's actions, it’s essential to look at the source material, the third novel in the trilogy, We’ll Always Have Summer, and contrast it with the latest developments in the TV show.

The Book: "We Were On a Break" and the Confession

In the original Jenny Han novel, the incident occurs when Jeremiah and Belly are going through a difficult period in their relationship. They are both away at college—Belly at Brown and Jeremiah at a different university—and the distance, combined with the lingering shadow of Conrad, creates tension.

  • The Context: Jeremiah travels to Cabo for a spring break trip. During this trip, he sleeps with another girl.
  • The Technicality: When Belly confronts him, Jeremiah insists they were on a break, or at least that their relationship was so precarious and strained that he believed it was over. The book leaves the technical definition of "cheating" ambiguous, but it is undeniably a massive betrayal of trust.
  • The Confession: Critically, Jeremiah is the one who eventually confesses the truth to Belly, showing a degree of accountability, though the damage is already done. This confession is the catalyst that sends Belly back into Conrad's orbit, as she realizes her relationship with Jeremiah is fundamentally broken.

The TV Show's Plot Twist: An Explicit Act of Unfaithfulness

The television series, particularly in the lead-up to the highly anticipated Season 3, has taken a much harder stance on Jeremiah's actions. Leaks and plot summaries suggest the show recontextualizes the incident to be a more explicit act of cheating, or at least one that is discovered in a more dramatic, less forgiving way.

  • The Framing: The show frames the incident as a clear act of cheating, or at least a betrayal that occurs while their relationship is still defined, making the "on a break" argument less valid in the eyes of the characters and the audience.
  • The Discovery: Instead of a clean confession, the show introduces more dramatic tension around the discovery. This revelation is often what pushes Conrad to intervene, solidifying the Team Conrad versus Team Jeremiah divide.
  • The Impact: In the show's narrative, this incident is a non-negotiable fracture point. It shatters Belly’s trust and directly contributes to her decision to call off the wedding, which is a key plot point from the third book that the series is adapting.

The difference is subtle but significant: The book presents a messy, realistic relationship failure rooted in a lack of communication, while the show uses the event as a clear, dramatic reason for Belly to definitively move on from Jeremiah.

The Cabo Incident: Accountability and the Proposal

The infamous "Cabo" trip is the geographical location of the betrayal, and the fallout from it defines the rest of Belly and Jeremiah's storyline. The narrative hinges on Jeremiah's response to the situation and Belly's reaction to his lack of accountability.

The betrayal comes at a time when the couple is already struggling with the pressures of college life and the lingering grief over Susannah's death. Jeremiah's actions, whether technically cheating or not, demonstrate a fundamental immaturity and an inability to handle conflict within the relationship. He acted impulsively and selfishly, which is what truly wounds Belly.

In a desperate attempt to fix the relationship after the betrayal, Jeremiah proposes marriage to Belly. This proposal, which is a major plot point in both the book and the expected Season 3 of the show, is an attempt to "band-aid" a deeply broken relationship. Belly, still reeling from the emotional fallout and perhaps clinging to the idea of a perfect future at Cousins Beach, initially accepts. However, the proposal is ultimately a distraction from the core issues.

The entity of Susannah Fisher's passing continues to influence this dynamic. The two brothers, Conrad and Jeremiah, and Belly are all coping with profound grief, and this emotional turmoil contributes to the poor decisions and communication breakdowns that plague the relationship.

The Final Breakup: Why Belly Chooses Her Own Path

The cheating/betrayal incident is not the sole reason for the end of Belly and Jeremiah's relationship, but it is the final, undeniable catalyst. The relationship was already facing insurmountable challenges, primarily the fact that Belly's heart was fundamentally split between the two brothers, and her deep, first love for Conrad never truly faded.

The cheating incident forces Belly to confront the reality of her connection with Jeremiah. She realizes that while she loves him—and he is her best friend—he is not her soulmate or the person she wants to marry. The relationship was built on ease, comfort, and a shared desire to move past the pain of the previous summer, rather than a deep, enduring, and reciprocal romantic passion.

The ultimate breakup is a mature, albeit heartbreaking, decision. Belly realizes that marrying Jeremiah would be a mistake for both of them. Key factors contributing to the final separation include:

  • Lack of Trust: The betrayal eroded the foundation of trust, making a future together impossible.
  • Jeremiah's Anger: Jeremiah's reaction to the breakup, where he blames Belly and acts out of anger, confirms for her that he lacks the emotional maturity she needs in a partner.
  • The Inevitability of Conrad: The incident pushes Belly to acknowledge that her feelings for Conrad are stronger and more enduring. Conrad's return and his unwavering love for Belly, even after the engagement, makes the choice clearer.

In the final resolution of the book series, Belly ends up calling off the wedding and eventually, years later, marrying Conrad Fisher. While the show has the freedom to diverge from the book, the core plot points of the Cabo incident, the proposal, and the final decision to end the engagement are essential to the narrative and are expected to be faithfully adapted in Season 3, even with the heightened drama around the "cheating" label.

Ultimately, whether you call it cheating or a betrayal during a break, Jeremiah's unfaithful act is the necessary tragedy that allows Belly to finally understand her own heart and find her way back to her true love at Cousins Beach.
