I saw he was going to marry her, for family, perhaps political reasons; because her rank and connexions suited him; I felt he had not given her his love, and that her qualifications were ill adapted to win from him that treasure. This was the point – this was where the nerve was touched and teazed – this was where the fever was sustained and fed: she could not charm him. (2.3.27, italics original)
I have not yet said anything condemnatory of Mr. Rochester’s project of marrying for interest and connexions. […] All their class held these principles: I supposed, then, they had reasons for holding them such as I could not fathom. It seemed to me that, were I a gentleman like him, I would take to my bosom only such a wife as I could love; but the very obviousness of the advantages to the husband’s own happiness, offered by this plan, convinced me that there must be arguments against its general adoption of which I was quite ignorant: otherwise I felt sure all the world would act as I wished to act. (2.3.31)
"What tale do you like best to hear?"
"Oh, I have not much choice! They generally run on the same theme – courtship; and promise to end in the same catastrophe – marriage."
"And do you like that monotonous theme?"
"Positively, I don’t care about it: it is nothing to me." (2.4.49-52)
