Marianne could never love by halves; and her whole heart became, in time, as much devoted to her husband, as it had once been to Willoughby.
What would the timeframe be here? See the time allowed for Reginald De Courcy to get over his first attachment and to have his feelings gradually turned, by his family, to someone else, in "Lady Susan":
"Frederica was therefore fixed in the family of her uncle and aunt till such time as Reginald De Courcy could be talked, flattered, and finessed into an affection for her which, allowing leisure for the conquest of his attachment to her mother, for his abjuring all future attachments, and detesting the sex, might be reasonably looked for in the course of a twelvemonth. Three months might have done it in general, but Reginald's feelings were no less lasting than lively."
