If I get married, I want to be very married.

The line expresses an insistence on wholehearted commitment rather than a tentative or performative version of marriage. “Very married” suggests a desire for depth—shared life, loyalty, and emotional presence—implying that marriage, for her, is not a casual milestone but an all-in partnership. Read against Hepburn’s public image (often treated as ethereal or detached), the remark underscores a practical seriousness about intimacy: if she enters the institution, she wants it to be real, sustaining, and fully inhabited. The phrasing also carries a hint of wit, using an exaggerated adverb to reject half-measures.
