Summary of "AITA for going ahead with my wedding without my father after his ultimatum?"

The video shares a deeply personal story about a woman who decided to go ahead with her wedding without her father after he gave her an ultimatum involving his new wife, who had been emotionally abusive toward her during her childhood. Key points include:

The woman lost her mother at age 11, and her father quickly remarried, introducing a stepmother who made her feel unwelcome and manipulated her father against her.
Despite attempts to maintain a relationship, the woman distanced herself by moving away for college.
Upon announcing her engagement, she chose to exclude her stepmother from the wedding guest list due to their toxic history.
Her father gave an ultimatum: either his wife attends the wedding or he won’t come.
She stood firm, refusing to invite the stepmother, leading to family backlash, social media defamation by the stepmother, and pressure from relatives to reconcile.
The father and stepmother even showed up uninvited to try to persuade her in person, but she remained resolute.
Emotional support came primarily from her fiancé and mother, while other family members sided with her father.
On the wedding day, the woman felt a sense of relief and empowerment, walking down the aisle with her mother’s memory and fiancé by her side.
After the wedding, her father sent a brief, late apology message without real remorse or effort to mend the relationship.
The woman concludes with acceptance, choosing to move forward without her father’s presence in her life.
