How does Rochester finally win a love confession from Jane?

Volume II/ Chapter VIII

One evening Jane runs into Mr. Rochester in the gardens. He reveals that he will marry Miss Ingram in a month and Jane must leave Thornfield; he already has another governess position lined up for her in Ireland. Jane is devastated at the prospect of being so far away from Mr. Rochester, but admits that Miss Ingram's presence will make such a separation necessary.

Mr. Rochester and Jane sit on a bench under a chestnut tree, and Mr. Rochester suddenly changes emotional positions. He tells her that he feels as if they are connected by a cord attached at the heart and asks her to stay at Thornfield. Jane refuses, bringing up the topic of his bride. She also argues that she must mean little to him if he is willing to marry someone so inferior to him as Miss Ingram. Admonishing him for his thoughtless cruelty to her, Jane confesses that she loves him. To her surprise, Mr. Rochester asks her to marry him.
