AITA for blaming my fiance for Thanksgiving being a disaster?
What happens when the family you grew up loving turns out to be something your partner’s family can’t accept — and your partner hides it for years? For many, explaining a non-traditional household feels vulnerable, especially when it involves polyamory.
One woman has always been open about her parents’ loving relationship with Rose, and thought her fiancé had shared it honestly with his own family. When the truth surfaced during Thanksgiving, the holiday turned awkward and tense — and the real fallout came when he refused to own his role in the deception.
‘AITA for blaming my fiance for Thanksgiving being a disaster?’
The poster’s family dynamic has been loving and stable since childhood.
Thanksgiving exposed the years-long deception.
The central conflict is a long-term deception that eroded trust. The fiancé avoided an uncomfortable conversation with his parents by lying — first by omission, then actively (claiming Rose was an “aunt”). This not only betrayed the poster’s openness but also put her family in an embarrassing position when the truth emerged naturally. His refusal to take responsibility (“it’s on his parents for being weirded out”) doubles the harm, shifting blame instead of owning the lie.
The poster’s anger is justified: she was clear from the start, trusted his assurance, and now faces fallout from his cowardice. His doubling down shows a pattern of conflict avoidance that could foreshadow bigger issues in marriage.
Relationship expert Dr. John Gottman has observed that “trust is built on small, consistent acts of honesty — and destroyed by hidden truths, even if the motive is fear” (The Science of Trust, 2011). Here, the fiancé’s lie by omission became active deceit, and his defensiveness blocks repair.
Practical advice: She should insist on accountability — a sincere apology, acknowledgment of the lie, and a plan to speak honestly with his parents. Premarital counseling is essential to explore his avoidance pattern. If he continues blaming others, it’s a serious red flag for long-term compatibility. Her feelings are not “crazy” — they’re a healthy response to betrayal.
These are the responses from Reddit users:
The online community overwhelmingly sided with the poster, calling her fiancé’s actions a major red flag and urging her to reconsider the engagement. Readers focused on the lie, lack of accountability, and potential future problems.
Most commenters firmly supported her anger and viewed the fiancé’s behavior as unacceptable:
Others shared personal experiences with polyamory and emphasized honesty:
This Thanksgiving disaster highlights how deeply lies — even those born from fear — can damage trust. The poster’s openness about her family was met with deception from her fiancé, leading to embarrassment for everyone and his refusal to own it. His blame-shifting and defensiveness are serious concerns for any long-term partnership.
The takeaway is that honesty, especially about family differences, must be mutual. Avoiding tough conversations doesn’t make them disappear — it only makes the fallout worse. If your partner lied about something important to avoid discomfort, would you see it as a one-time mistake or a pattern worth reevaluating? How much does accountability matter before marriage?
