Final answer:
Antigone believes the curse of her incestuous family heritage is destroying her future, specifically her marriage to Haemon, due to her actions and the judgments of others like Creon.
Step-by-step explanation:
Antigone reflects on her doomed family lineage and the impact of her father Oedipus's actions on her own life. She laments that the incestuous marriage of her parents has led to a curse that affects her relationship with her betrothed, Haemon. In Sophocles' play Antigone, she indicates that the legacy of her family history has come back from the past to destroy her future, including her marriage. The chorus and other characters in the play, including Antigone's sister Ismene and her fiancé Haemon, also reveal the ripple effects of familial tragedy and the strictures of destiny.
