AITAH for telling my dad that I do not want to be his best man at his wedding?

A 16-year-old boy lost his mom to a devastating car accident three years ago, leaving her in a persistent vegetative state until treatment stopped. In the midst of that grief, his dad introduced—and soon got caught with—a woman who quickly became central to their lives.

Now, with the wedding approaching, dad assumed his son would happily serve as best man. When the teen said no and admitted he might skip the event altogether tensions exploded. The house feels colder, the fiancée keeps pushing for apologies, and he’s left wondering if his honesty makes him the bad guy.

‘AITAH for telling my dad that I do not want to be his best man at his wedding?’

The accident happened when he was 13, shattering their family. Seven months later, dad brought home Alyssa as an “old friend”:

One night in November 2021, he caught them kissing on the couch—while mom was still alive:

The wedding talk escalated when he overheard them planning his role as best man without asking:

Dad was hurt, things grew awkward, and Alyssa now pushes for him to apologize:

Grief in teenagers is already complex—losing a parent to prolonged illness adds layers of unresolved pain. When a surviving parent moves forward quickly, children often feel their loss is minimized, creating lasting resentment.

Family therapist Dr. Joshua Coleman, specializing in estrangement, notes that rushed repartnering can feel like betrayal to kids still mourning. The request to stand as best man isn’t just logistical—it’s symbolic, asking the child to publicly endorse a union tied to painful memories.

Healing often requires acknowledgment: the parent validating the child’s timeline of grief rather than expecting immediate acceptance. Joint counseling—without the new partner initially—can create space for honest processing before rebuilding trust.

Long-term, teens benefit from preserving connections to the lost parent: keeping photos visible, sharing stories, honoring milestones. When those feel erased, protective boundaries like refusing ceremonial roles become natural self-preservation.

Here’s what Redditors had to say:

The community overwhelmingly declared the teen NTA, praising his maturity while condemning the dad’s timing and erasure of mom:

Many urged protecting mom’s belongings and seeking outside support:

Several highlighted the betrayal and suggested therapy or distance:

One offered a darkly humorous revenge speech idea:

Every commenter agreed the teen is NTA—his pain is valid, his boundaries reasonable, and his dad’s rush forward deeply hurtful. Many encouraged therapy, safeguarding mom’s items, and building independence.
