Gadea married Guevara in Mexico in September 1955, after learning she was pregnant. The marriage ended in a divorce in May 1959. They had a daughter named Hilda Beatriz "Hildita" Guevara Gadea in February 1956 who died of cancer in 1995.[4]
Following the Cuban Revolution, in which Guevara fought, Gadea came to Cuba, to be confronted with the announcement by Guevara that he had fallen in love with another woman, Aleida March, and requested a divorce. Gadea remained loyal to Guevara's political movement; she died in Havana in 1974.[4] She wrote the memoir My Life With Che.[2] Gabriel San Roman, a writer for Z Magazine, began writing a play about Gadea.[5]
