Discovering a spouse’s infidelity is probably one of the most devastating experiences a person can face. And beyond the immediate betrayal, it can shake the foundation of trust, leave really deep emotional scars, and affect relationships with family and friends.

After today’s Original Poster (OP) discovered her husband’s infidelity, her mother-in-law came around and offered unsolicited advice about saving the marriage. However, the OP asked her a question that left the mother-in-law stunned.

She clarified that she made it up, and that she mentioned it just so that the mother-in-law would leave her alone

The OP shared that she married but discovered her husband had been unfaithful . In fact, he left her with an infection, and that was what revealed the affair in the first place when they got into a fight. After the discovery, she made the decision to file for divorce and began packing up to leave the house.

While she was preparing to move out of the home owned by her mother-in-law who had previously offered cheap rent, the mother-in-law arrived uninvited. Rather than offering support, she urged the OP not to “give up so easily” and insisted she work through the marriage. In turn, the OP asked her mother-in-law how she had dealt with infidelity in her own marriage, specifically referencing an alleged affair from years earlier.

The mother-in-law denied knowing what she was talking about, became flustered, and left shortly after. The OP made sure to note that the story itself wasn’t true, but that she had made it up so her mother-in-law would leave her alone.. However, she heard that it caused a huge fight between her mother-in-law and the father-in-law.

Infidelity is widely recognized as a leading contributor to divorce around the world, and PsychiCare affirms this. According to them, couples often struggle to recover from the deep breach of trust that affairs create, and the emotional fallout can affect both partners’ mental health as well as their future relationships.

In some cases, the aftermath of betrayal can also highlight patterns of behavior shaped by unmet emotional needs. Just like the OP, Resolve explains that people may invent or exaggerate situations to elicit sympathy or attention when they feel neglected, insecure, or unsupported.

Given the emotional toll of infidelity, experts stress the importance of setting clear boundaries to support recovery. According to Grow Counseling , boundaries help restore a sense of safety and agency, giving the betrayed partner control over their emotions and decisions.

This might include cutting all contact with the affair partner, digitally or indirectly, to prevent further harm and safeguard trust. Establishing these limits allows the couple to prioritize reconciliation while giving both individuals space to process the betrayal and rebuild a healthier , more secure relationship.

Netizens sided with the OP, highlighting the toxic family dynamics, especially the father-in-law’s role in covering up the affair. Others focused on the boldness and humor in her approach, admiring her unapologetic stance even if some found it controversial. What do you think? Can lying to make a point ever be justified, or is honesty always the best policy? We would love to know your thoughts!
