AITA for refusing to go to my sister’s wedding, knowing that it means most of our family won’t attend?

A 40-year-old woman has been low-contact with her parents and younger sister for years due to childhood feelings of being parentified and overlooked after her sister’s birth. When her sister asked her to be in the wedding party, she assumed it would be child-free because the sister knows she is deeply uncomfortable around children — a trigger tied to past trauma.

During planning, the sister revealed children (flower girl, ring bearer, and many others) would attend. The woman felt betrayed and reminded of being “thrown aside” as a child, so she declined. After her sister accepted her choice, she posted vaguely on Facebook that she had been “kicked out” of the wedding over “trauma they caused.” Now many family members are refusing to attend unless she is reinstated. Is she the asshole?

The backstory involves long-standing resentment:

The Facebook post caused fallout:

Current stance:

The woman’s childhood feelings of being parentified and overlooked are valid and painful. Hand-me-downs alone do not constitute parentification — but if they were part of a larger pattern of emotional neglect or responsibility displacement, the hurt is real. Her discomfort around children as a trauma response is also legitimate; many people with similar backgrounds develop strong aversions.

However, the wedding is her sister’s day — not hers. Expecting a child-free event based on personal trauma (without explicitly discussing it beforehand) places an unreasonable burden on the bride. The Facebook post, framed as being “kicked out” while omitting her own refusal to attend due to children, is manipulative. It weaponized family sympathy to punish the sister and parents.

Therapist and trauma specialist Dr. Mariel Buqué notes that unhealed parentification can lead to black-and-white thinking and difficulty seeing others’ perspectives. The woman’s post and refusal to retract it (fearing she’ll look like a liar) suggest she is prioritizing control and revenge over repair. Attending or not is her right — but publicly misrepresenting the situation to rally family against her sister crosses into AH territory. Therapy should focus on separating past pain from present relationships.

Here’s how people reacted to the post:

The overwhelming majority of commenters called the OP YTA, criticizing her entitlement, manipulation, and refusal to accept that the wedding is not about her:

A small number of comments showed some empathy for the trauma but still concluded YTA due to the Facebook post and refusal to accept the sister’s choice:

The woman’s childhood pain and discomfort around children are real and deserve compassion. However, the wedding belongs to her sister — not her. Expecting a child-free event based on personal trauma (without prior negotiation) is unreasonable, and publicly misrepresenting the situation as being “kicked out” to rally family support is manipulative.

She has every right to decline the invitation, but the Facebook post crossed into AH territory by omitting key context and weaponizing family sympathy. Therapy is already underway — the next step is accepting that her sister’s choices are not an attack on her mother’s memory or her worth. Attending or not is her call; deliberately sabotaging the event is not.
