Whether cheating is a deal breaker depends less on the affair itself and more on what follows. For some, infidelity permanently shatters trust and walking away is the healthiest choice. For others, accountability, remorse and sustained effort make reconciliation possible. There is no universal rule. Every marriage has different boundaries, different histories and different definitions of what can and cannot be forgiven. The debate, perhaps, isn’t simply about cheating, it is more about whether trust, once broken, can truly be rebuilt.
