In her 1880 memoir "A Blighted Life," Lady Rosina Bulwer-Lytton exposed the marital abuse and persecution she experienced from her husband, novelist Edward Bulwer-Lytton, Baron Lytton.

She also included some very choice words about her husband's close friend Charles #Dickens!

The fractious marriage between the Bulwer-Lyttons had been the talk of London since 1839, when Rosina based the character Lord de Clifford on her husband in "Cheveley, or the Man of Honour."

Contemporaries clearly registered shock at this scandal! https://www.google.com/books/edition/Cheveley_Or_The_Man_of_Honour/f2tA8oXTNGcC

Besides taunting her with a stream of mistresses, being physically violent, and depriving her of financial support and personal earnings, Bulwer-Lytton had her followed, sent his wife to a madhouse before she managed to escape, and allegedly attempted to poison her

In "A Blighted Life," written cir. 1864, Lady Bulwer-Lytton gratefully addresses Charles Reade.

His "Hard Cash" (1863), serialized in #Dickens's periodical "All the Year Round," explored the experiences of those wrongly imprisoned under England's as-yet unreformed lunacy laws

Responding to Reade's call for reports of such abuse, Bulwer-Lytton shows her disdain for Dickens:
"But your Novel I have not read, having a horror of all things that emanate from or appear under the auspices of that patent Humbug, Mr. CHARLES DICKENS, or any of his clique" (4)

Speaking of her husband, Bulwer-Lytton argues, "one has only to look at his hideous face, and that of that other brute, DICKENS, to see that every bad passion has left the impress of its cloven hoof upon their fiendish lineaments" (9)

Later she mocks Dickens's use of grammar!

Likely, Rosina Bulwer-Lytton despised Dickens for his similar behavior towards Catherine Hogarth, from whom he had very publicly separated.

It is unknown if the author knew of his brief attempt to have Catherine sent to a madhouse: https://www.york.ac.uk/news-and-events/news/2019/research/dickens-letters-asylum/

Supplementary materials added in 1880 by her editor suggest the "humbug" and "blackguard" Dickens may have played an influential part in obscuring Bulwer-Lytton's domestic issues from the press, though the whole truth remains to be established by scholars
