5 Shocking Reasons Belly And Jeremiah’s Wedding Was Called Off In The Summer I Turned Pretty Show’s Finale

The question that has split the fandom since the first season finally has a definitive answer. As of the latest, most current information available in December 2025, Belly does not marry Jeremiah Fisher in The Summer I Turned Pretty show. The highly anticipated, and controversial, wedding between Isabel "Belly" Conklin and Jeremiah is a central plot point of Season 3, which adapts the final book in Jenny Han’s trilogy, We’ll Always Have Summer. However, in a dramatic and emotional finale that sent shockwaves through Cousins Beach, the wedding is ultimately called off, confirming the show's direction follows the source material's major heartbreak before its final resolution.

This storyline, which was the backbone of the final season, served as the ultimate test for the love triangle, forcing Belly to confront her true feelings for both Jeremiah and his older brother, Conrad. While the show's creator, Jenny Han, had previously teased that the series ending might "surprise" fans, the core emotional beats of the book's conclusion—the almost-wedding and the final choice—remained intact, providing a satisfying, albeit devastating, closure for Team Jelly fans.

The Definitive Relationship Arc: Belly, Jeremiah, and Conrad's Journey

To truly understand why the wedding was doomed from the start, one must look at the tumultuous and deeply intertwined history of the three central figures. The final season’s drama is a culmination of years of repressed feelings, miscommunication, and the profound loss of Susannah Fisher, which initially brought Belly and Jeremiah closer together. The relationship arc of the central love triangle is the heart of the entire series, driving every major plot decision.

• Isabel "Belly" Conklin (Lola Tung): The protagonist whose 16th summer changes everything. Belly's journey is defined by her quest for a "forever" love, initially believing she found it with Jeremiah. Her character development centers on moving past the idealized, childhood version of love and choosing a mature, stable partnership.
• Jeremiah Fisher (Gavin Casalegno): The "golden retriever" younger brother. Jeremiah’s relationship with Belly is one of passionate, immediate connection and fun. Their bond is strong, but the series consistently explores the underlying insecurity in their connection, especially in the shadow of his brother. His character arc in the final season deals with the pressure of commitment and a major transgression that shatters Belly’s trust.
• Conrad Fisher (Christopher Briney): The brooding, intense older brother. Conrad represents Belly's "first love" and her "infinite" love, a connection that is intellectual, deep, and often painful due to his emotional guardedness. His presence is the constant, unresolved tension that hangs over Belly and Jeremiah’s relationship, proving that some connections are too strong to break.

The decision to get married, made by Belly and Jeremiah during their college years, was presented as a defiant, impulsive act—a way to cement their relationship against the world and the lingering presence of Conrad. This rushed engagement, however, was a significant departure from the steady, mature love that Belly ultimately seeks.

The Shocking Plot Twist That Stopped the Wedding

The entire premise of the third book, We’ll Always Have Summer, and subsequently, the third season of the show, revolves around the imminent wedding and the escalating tension between the brothers. The ceremony, set to take place at the beloved Cousins Beach, was meant to be Belly and Jeremiah's happily ever after, but a massive secret revealed just before the vows brought everything crashing down.

The central bombshell that derails the wedding is the revelation that Jeremiah cheated on Belly during a break in their relationship, specifically during his bachelor party weekend. Conrad, who attends the bachelor party, is the one who learns the truth about Jeremiah's infidelity. This secret puts Conrad in an impossible position: protect his brother or protect the woman he loves from a lifetime of hurt. In a moment of high drama, the truth is exposed, forcing Belly to face the reality of her relationship.

This act of betrayal is the ultimate catalyst. It forces Belly to realize that her desire to marry Jeremiah was, in part, a way to escape the pain of her breakup with Conrad and to hold onto the familiar comfort of the Fisher family. The cheating scandal proves that their rushed, emotionally charged engagement was built on shaky foundations, leading to the painful but necessary decision to call off the wedding before the ceremony even begins.

Book vs. Show: Will Jenny Han Change the Final Ending?

One of the most intense debates among the fandom leading up to the final season was whether the show's creator, Jenny Han, would adhere to the book's definitive ending or create a new one. Han has been vocal about having "14 years to stew" on the original ending and has teased that the show could leave fans "devastated" or "surprised," suggesting a potential deviation.

However, the plot points revealed for Season 3 strongly indicate that the show is committed to the main trajectory of the book, which is a Conrad endgame. The key differences are likely to be in the journey, not the destination. For example, the show dedicates more time to exploring the depth and validity of Belly's relationship with Jeremiah, making the final decision even more emotionally complex for viewers.

In the third book, *We’ll Always Have Summer*, after the called-off wedding, Belly and Jeremiah break up. Several years pass, during which Belly and Conrad slowly find their way back to each other. The book concludes with a flash-forward to a 23-year-old Belly finally getting married—to Conrad—at Cousins Beach, the place where their story began.

The 5 Phases of Belly’s Final Choice Between Conrad and Jeremiah

The journey to Belly's final decision is a multi-step process that spans the entire final season. It is not an abrupt choice but a gradual realization of who her true "forever" love is. These five phases mark the end of the love triangle:

1. The Impulsive Engagement: Belly and Jeremiah get engaged in a moment of youthful defiance and a desire to hold onto their summer life, which is the immediate setup for the conflict.
2. The Cheating Revelation: The discovery of Jeremiah's infidelity is the first major crack, forcing Belly to question the trust and maturity of their bond.
3. The Confrontation and Canceled Wedding: Belly and Jeremiah have a tearful, public confrontation where they both realize they are trying to force a future that isn't meant to be, leading to the wedding being called off.
4. The Paris/Airport Reconciliation: Following the disaster, Belly leaves for Paris (or is seen at the airport), where she and Conrad have a crucial, honest conversation, beginning the slow process of their reconciliation and acknowledging their "infinite" connection.
5. The Final Endgame: After a necessary time jump, the series concludes with Belly and Conrad reuniting and eventually marrying at Cousins Beach, confirming that Conrad was Belly's endgame all along.

Ultimately, while Belly and Jeremiah come close to tying the knot, they do not get married in The Summer I Turned Pretty show. The final season uses their near-wedding as the emotional climax, providing the necessary heartbreak for Belly to finally understand that her destiny, her true "infinity," lies with Conrad Fisher.
