At Thornfield, Jane Eyre declares herself Rochester's equal before she knows he means to marry her. Much later she returns to him able to say something more practical: she has money of her own and can choose whether to stay. Between those moments Brontë gives her two proposals. One man loves her and tries to place the relationship outside the truth of his existing marriage. Another offers her a respectable marriage while making clear that he wants a fellow worker rather than a beloved person. Jane's answer to each is shaped by the same demand. A bond must have room for the particular people who are in it.
That demand makes Jane an illuminating ESI reading. In the ESI configuration, Model A places Fi, Relations, at Base and Se, Force, at Creative. Model L gives these positions the more particular names Fi(S.) Animus and Se(F.) Impetus. Animus names the settled, embodied character of an attachment or aversion to someone in particular. Impetus is the capacity to bring that judgement into the world: to hold a line, leave a place, return, or offer one's help on chosen terms. Jane's story is full of feeling, but Brontë makes feeling answerable to the actual relation it can sustain.
The first proposal begins with a false separation
In chapter XXIII of Jane Eyre, Rochester tells Jane that he expects to marry Blanche Ingram and that Jane must take another position in Ireland. The imagined move would remove her from him, from Adèle and from the life she has made at Thornfield. His speech is a contrivance: he wants her to disclose how much she cares before he tells her what he intends. Jane does disclose it. But the pressure also elicits the clearest account of what is wrong with treating a governess as a convenient piece to be moved. She asks whether he takes her for a machine without feelings, then insists that spirit speaks to spirit as an equal.
The scene has often been read, rightly, as a demand for equality. Sally Shuttleworth's British Library account places that demand against the narrow, uncertain social position of the nineteenth-century governess. Jane lives inside a household without belonging straightforwardly to either family or servants. Rochester's invented Irish appointment exploits that dependence. Yet Jane's reply is more exact than a claim to equal rank. She names the bond he is pretending to sever. Her love is not gratitude for a salary or an aspiration to become a lady. It attaches to this person, with his difficult humour, his attention to her, and the life they have shared. She can stand before him as an equal because she knows what she is saying about him.
Rochester seems to meet her there. He asks her to marry him, and speaks of her as his equal and likeness. Still, the earlier performance matters. He has brought Jane to confession by pretending to control where she will live. He can recognise the strength of her feeling while continuing to direct the scene in which it is spoken. Brontë lets the proposal be both genuinely desired and structurally uneasy. Jane accepts the man, but the conditions under which she can become his wife have not yet been told to her.

Love cannot rename the fact
At the interrupted wedding, Rochester's living marriage to Bertha Mason becomes public. Jane then faces an argument far more seductive than a simple command. Rochester asks her to go with him to France and live as his wife in every sense he says should matter. He promises fidelity and a private life guarded from the injury that has already been done. In chapter XXVII, Jane answers by refusing his chosen description. Bertha is alive; if Jane lives with Rochester on these terms, she will be his mistress. Calling her a wife in private cannot create the public relation the word names.
Her exactness can be mistaken for obedience to a rule at the expense of love. The scene resists that reading. Jane tells Rochester she loves him more than ever. She also knows she could not remain near him and continually restrain that love. Departure costs her the person and the home she most wants. Her decision protects the integrity of the attachment itself. If she lets Rochester's need determine the name and conditions of the bond, she will be made into a secret exception to the life he has actually lived. The man she loves is also the man who has concealed Bertha and has tried to make concealment the basis of their future.
Fi(S.) Animus helps distinguish the force of this judgement from an abstract preference for moral purity. Jane's claim concerns these people and this history. Bertha's continuing existence cannot be edited out of the relation by an intensity of feeling between Jane and Rochester. Nor can Jane's own position be repaired by a private assurance. An ESI reading begins with the particular bond as a concrete reality, including what each person has done and what others remain entitled to claim. The matter is intimate enough that a false name for it would deform it.
Se(F.) Impetus comes into view when Jane turns that settled judgement into an act. She leaves Thornfield before dawn with little money or prospect. Brontë does not make this a clean victory over desire. Her flight brings hunger and near collapse. The action matters because she carries it through despite wanting the opposite. In Model L terms, the creative force serves the primary relational judgement: she leaves because staying would let Rochester's version of their bond displace her own knowledge of it. The departure gives her feeling a boundary that can survive its own intensity.
A role without a beloved person
The Rivers household gives Jane kinship, work and an inheritance. St John Rivers then presents the second proposal. He admires her discipline and usefulness. He wants her to accompany him to India as a missionary's wife. The proposal has the form of an honourable, publicly recognisable marriage, but St John says plainly that Jane is formed for labour rather than love. When she says she has no vocation, he treats her answer as an obstacle he can overcome by assigning and supervising her tasks. In chapter XXXIV, he speaks for what he thinks her heart should say.
Jane is willing to work with him as a sister. The distinction is crucial: she does not reject arduous service simply because it is hard. She refuses to make marriage the instrument of a project in which no husband and wife meet as such. St John's design has a place for her abilities, but not for her own affection or choice of a beloved. The proposal turns a relation into an office. Later, explaining herself to Diana, Jane says St John wants to mate his office and describes the threatened marriage as life with someone who regards her as a useful tool. Her words identify the missing person inside an apparently respectable arrangement.
St John's offer throws Rochester's into sharper focus. With Rochester, Jane is loved and asked to accept a private fiction in place of a lawful relation. With St John, she is offered lawful marriage and asked to live without the reciprocal feeling that would make it hers. These are not merely two varieties of male pressure. They separate components Jane refuses to separate: affection for an actual person, truthful recognition of the relation, and the freedom to consent to its shared life. Her judgement has become more articulate because each offer isolates something she needs from the rest.

Returning is a positive act
Jane's return to Rochester in chapter XXXVII is sometimes told as the moment fate finally permits the lovers to reunite. Brontë gives it a more material and more interesting sequence. Jane has inherited money and divided it with her newly found cousins. She is no longer Rochester's employee, and she has a family beyond his house. Bertha has died in the fire at Thornfield. Rochester has lost the house, his sight and a hand. None of these events makes him a better person by magic; together they alter what Jane can truthfully offer and what he can now ask her to bear.
She tells him she is independent. When he wonders whether she will stay, she says she could even build her own house nearby and invite him to visit. The remark is playful, but it is also a measure of changed terms. She can offer companionship without needing shelter from him. When she volunteers to read, walk and care for him, Rochester objects that he has hated being led by a hired attendant. Jane's help is different because it comes from Jane. The same act acquires another character through the particular relation between giver and receiver.
Rochester asks if she would sacrifice herself to care for his injuries. Jane rejects the premise. Being useful to the person she loves is a delight, especially now that he can receive from her what he formerly insisted on being the one to give. This is no fantasy of perfectly equal capacities. He needs assistance; she chooses to give it. Their difference can belong within the bond because neither needs to disguise the other's personhood. Her independence is what lets her care be an offering instead of a condition of survival.
There remains resistance in the ending. Rochester is still capable of old impatience, wanting an immediate wedding. Jane turns the conversation toward the ordinary hour and a meal. Brontë does not freeze the pair in a final pose of perfect harmony. Their relation now has to be lived, adjusted and spoken by both of them. The famous opening of the last chapter, Reader, I married him
, places Jane as the grammatical actor of the event. The sentence is short because the novel has spent so long making her choice intelligible.

The shape of fidelity
The Model A distinction between Base and Creative gives Jane's sequence its Socionics contour. Fi at Base is the abiding question of whom she loves, trusts and can stand beside. Se at Creative gives that judgement consequence. She speaks under Rochester's feigned dismissal, leaves when love is offered on a false basis, resists St John's assignment, and returns when she can give herself without surrendering her standing. Those actions are unlike one another in tone. Their continuity lies in what each protects or makes possible.
Jane's ESI reading therefore has a positive centre. Fidelity is not simply staying, and force is not simply refusing. The relation she wants must be true to the lives of the people in it and capable of being enacted in their world. She does not preserve love in a sealed interior space while circumstances change around it. She makes decisions that give it a habitable form. By the end, attachment and independence have ceased to compete for the same place: her chosen care is the act through which both become visible.
