OP, a 17-year-old, found herself in a complex emotional situation when her dad, who had been absent from her life since she was 5, showed up at her great-grandma's 100th birthday party with his new family. Observing her dad being actively involved and caring with his new kids, she felt a mix of emotions, given the lack of such engagement during her childhood.
When her dad approached her with a somewhat awkward greeting, OP, expressing her hurt and frustration, sarcastically congratulated him on being a dad to his new children.
Her dad, in response, acknowledged the past but claimed he couldn't change it. However, OP pointed out that he currently makes no effort to maintain a relationship with her. The family members at the event took issue with OP's reaction, telling her to grow up and be happy for her dad.
Is OP The AH in this case? Let's hear Reddit's verdict.
