1847, when she had to give him up.

The ever faithful Delphine knew of Balzac's financial embarrassment
and persuaded her husband to postpone pressing him for the debts which
he had partially paid before setting out for the Ukraine. The
Revolution of February seriously affected Balzac's financial matters.
After the death of Madame O'Donnel, in 1841, Madame de Girardin's
friendship lost a part of its charm for Balzac and the rest of it
vanished in these troubles. Since the greater part of the last few
years of Balzac's life was spent in the Ukraine, she saw but little of
him, but she hoped for his return with his long sought bride to the
home he had so lovingly prepared for her in the rue Fortunee.

Whether Balzac was fickle in his nature, or whether he was trying to
convince Madame Hanska that she was the only woman for whom he cared,
one finds, throughout his letters to her, various comments on Madame
de Girardin, some favorable, some otherwise. He admired her beauty
very much, and was saddened when, at the height of her splendor, she
was stricken with smallpox. He was grateful to her for the service she
rendered him in arranging for the first presentation of his play
_Vautrin_, throughout the misfortune attending this production she
proved to be a true friend. Although he accepted her hospitality
frequently, at times being invited to meet foreigners, among them the
German Mlle. De Hahn, enjoying himself immensely, he regretted the
time he sacrificed in this manner, and when he quarreled with her
husband, he expressed his happiness in severing his relations with
them. While a charming hostess at a small dinner party, she became,
Balzac felt, a less agreeable one at a large reception, her talents
not being sufficient to conceal her _bourgeois_ origin.
