Seeing his devotion to her, one can understand why he begged her to spare him neither counsels, scoldings nor reproaches, for all were received kindly from her.  One can perceive also the sincerity of the following expressions of friendship: 

“You are right, friendship is not found ready made.  Thus every day mine for you increases; it has its root both in the past and in the present. . . .  Though I do not write often, believe that my friendship does not sleep; the farther we advance in life, precious ties like our friendship only grow the closer. . . .  I shall never let a year pass without coming to inhabit my room at Frapesle.  I am sorry for all your annoyances; I should like to know you are already at home, and believe me, I am not averse to an agricultural life, and even if you were in any sort of hell, I would go there to join you. . . .  Dear friend, let me at least tell you now, in the fulness of my heart, that during this long and painful road four noble beings have faithfully held out their hands to me, encouraged me, loved me, and had compassion on me; and you are one of them, who have in my heart an inalienable privilege and priority over all other affections; every hour of my life upon which I look back is filled with precious memories of you. . . .  You will always have the right to command me, and all that is in me is yours.  When I have dreams of happiness, you always take part in them; and to be considered worthy of your esteem is to me a far higher prize than all the vanities the world can bestow.  No, you can give me no amount of affection which I do not desire to return to you a thousand-fold. . . .  There are a few persons whose approval I desire, and yours is one of those I hold most dear.”

Among those to whom Balzac could look for criticism, Madame Carraud had the high intelligence necessary for such a role; he felt that never was so wonderful an intellect as hers so entirely stifled, and that she would die in her corner unknown. (Perhaps this estimate of her caused various writers to think that Madame Carraud was Balzac’s model for the femme incomprise.) Balzac not only had her serve him as a critic, but in 1836 he requested her to send him at once the names of various streets in Angouleme, and wished the “Commandant” to make him a rough plan of the place.  This data he wanted for Les deux Poetes, the first part of Les Illusions perdues.

Like his family and some of his most intimate friends, she too interested herself in his future happiness, but when she wrote to him about marriage, he was furious for a long time.  Concerning this question, Balzac informs her that a woman of thirty, possessing three or four hundred thousand francs, who would take a fancy to him, would find him willing to marry her, provided she were gentle, sweet-tempered and good-looking, although enormous sacrifices would be imposed on him by this course.  Several months later, he writes her that if she can find a young girl twenty-two years of age, worth two hundred thousand francs or even one hundred thousand, she must think of him, provided the dowry can be applied to his business.
