AITAH for Blocking And Silently Moving On From My Cheating Fiance?

When betrayal strikes, the path to healing can be both personal and uncompromising. Our OP, a 31‑year‑old woman, shares her difficult decision to cut ties with her ex-fiancé after discovering his long-term infidelity. For five years, she believed in their future together—until she found out he had been cheating with a coworker for nine months before their engagement.

The shock and hurt were so overwhelming that, after hours of crying and reflection while he was on a work trip, she resolved to move on without giving him another chance. Packing her belongings and asking her father for help, she began to untangle their lives, leaving behind even the physical symbols of their shared past.

Now, with her parents urging her to reconsider and hear his side, OP stands firm, questioning whether she owes a cheater any explanation at all. As she tours apartments and plans her fresh start, she wonders if her decision to block him and silently move on makes her the asshole—or if it’s the healthiest choice for her future.

Dr. Ramani Durvasula, a clinical psychologist known for her work on relationship trauma, explains, “When a partner’s betrayal undermines your self-worth, it’s natural to feel compelled to sever ties to protect yourself. The decision to cut off communication after infidelity, especially one that spans months, is a powerful form of self-care—provided it’s not made in a moment of impulsivity.” (kidshealth.org)

Family therapist Dr. Susan Johnson adds, “Healthy relationships require a foundation of trust and mutual respect. When that trust is shattered, as in cases of prolonged cheating, it’s entirely reasonable to choose to move on rather than try to salvage a relationship built on broken promises. While some may argue for hearing the other side, it’s important to recognize that not every relationship can or should be repaired, particularly when the hurt runs this deep.”

Both experts emphasize that while reconciliation is ideal in some cases, the decision to block a partner and move on is a valid, if painful, step toward healing when trust is irreparably broken.

Here’s how people reacted to the post:

Many redditors empathize with OP, noting that after such a betrayal, moving on without further explanation is not only understandable but sometimes necessary. “If you’ve been cheated on for nine months, you don’t owe that person a second conversation,” one commenter stated.

Ultimately, the decision to block and move on from a cheating partner is intensely personal and can be a necessary step toward healing. OP’s actions—while they may seem abrupt to some—reflect a deep commitment to protecting her self-worth and prioritizing her future. The fact that her fiancé betrayed her trust for an extended period makes it understandable that she would not want to give him another chance or hear his side.

What do you think? Is it fair to cut off communication with a cheater without further discussion, or should there be room for closure, however painful it may be? Share your thoughts and experiences in the comments below—what would you do if you found yourself in a similar situation?
