I think the author recognizes that she had no duty to her father after the abuse she suffered and that nobody she cared about would think twice about her never seeing him or his family again. Reading between the lines I heard the voice of a young girl who will nonetheless always miss the father figure she wanted (so desperately that she was ready to forgive and forget sexual abuse if he would either apologize or lie to her about it) but never had (because he never existed) and these emotions become triggered by any mention of his name. I've had close friends in this situation and the psychology of it can become very frustrating and confusing. In any case the article wasn't about him, it was about herself - probably written, she would say, for others in her situation with less self-awareness or self-confidence - children who should recognize a duty not to an abusive parent but to themselves to achieve some measure of peace and closure in their own lives.
