Allah the Exalted says that when the woman who is in her `Iddah nears the end of the `Iddah term, the husband must decide to reconcile with her, thus keeping their marriage together,

﴿بِمَعْرُوفٍ﴾

(in a good manner) while being kind to her in their companionship. Otherwise, he must decide to divorce her on good terms, without abusing, cursing, or admonishing her. To the contrary, he should divorce her on good terms, observing kindness and good manners.
