She became a chair member of the Ateneo Mexicano de Mujeres and later moved back to Cuba, where she wrote the radionovela Yo no creo en los hombres, which was adapted in Mexico for telenovelas in 1969 and 1988.
Back in Mexico, she wrote Corazón salvaje, a novel that has been adapted to the screen twice and as a telenovela four times (including once as Juan del Diablo in Puerto Rico).
Though she has her own style of writing, Caridad's most successful stories are the ones in which she deals with the Margaret Mitchell-like topic of loveless marriage and the process of conquering one's wife.
Just like Mitchell, Caridad explores the human psychology from the perspective of a protagonist who ignores her true emotions and goes through a process of realizing the feelings that were there all along.
Her female figure on the other hand varies keeping as only thing in common with Mitchell's Scarlet O'Hara, her strength of character and stubbornness.
