Jeyne Westerling, Talisa and Two Kinds of Broken Promise
Robb's marriage has a similar political consequence in both versions, but its emotional logic is strikingly different.
Spoiler scope: A Storm of Swords and television seasons 2–3, including the Red Wedding.

A decision with different roots
Robb Stark breaks a marriage agreement in both the novel and the television adaptation. The surface similarity can conceal a substantial change. The book's Jeyne Westerling and the show's Talisa are different characters, with different relationships to his campaign and different narrative functions. Treating Talisa as merely a renamed Jeyne obscures the reason this adaptation choice matters.
In the novel, Robb's decision is closely entangled with his understanding of honour and his responsibility towards Jeyne after an intimate encounter. In the show, the relationship with Talisa develops through conversations and attraction that foreground a conflict between personal desire and a public arrangement. The resulting alliance problem may resemble its counterpart, but the route there encourages a different judgement of the king.
Public duty does not cancel private obligations
The book version is especially uncomfortable because honour does not point in one direction. Protecting one person's reputation can violate a promise made to secure military support. Robb cannot satisfy every obligation simply by trying harder to be decent. The inherited language of duty offers competing commands, and the war makes their collision consequential for people who had no part in the original decision.
The television romance makes his refusal of the political marriage more visibly deliberate. That can make the emotional choice easier to follow while making the breach harder to explain as an unavoidable conflict of duties. Neither reading excuses the violence later committed against him. A broken bargain and an atrocity are not morally equivalent responses within a neutral contract dispute.
The difference at the wedding
Talisa attends the Red Wedding and is killed. Jeyne does not occupy that position in the novel's event. The screen choice concentrates the consequences of the romance into the same sequence, giving the audience an immediate image of a future destroyed. The book leaves a different aftermath, with survival becoming part of the continuing political landscape rather than a restoration of happiness.
A productive comparison separates three questions: why Robb marries, how the marriage changes his alliances, and what the narrative does with his wife afterwards. Collapsing them into a single debate about whether love caused his defeat misses how adaptation can preserve a plot junction while changing the ethical argument that leads to it.
The same broken promise can arise from different obligations—and make a character seem different even before the consequences arrive.
