please help me maria is a convincing character according to from whom the bell tolls

"Some critics of For Whom the Bell Tolls consider Maria a weak link in the novel because her characterization depends so heavily on the effect she has on Robert Jordan rather than on her own motivations and conflicts. These critics argue that Maria’s submissiveness and the speed with which her affair with Robert Jordan progresses are unrealistic. They assert that Maria is not a believable character but rather a stereotype or the embodiment of a male fantasy. Some feminist critics have blanched at Hemingway’s treatment of Maria’s rape, especially at the fact that sexual intercourse with Robert Jordan appears to heal Maria instantaneously. But although Maria does come across as a rather static character, this flatness renders her symbolic importance all the more apparent. Maria’s lovely image endures beyond the last pages of the novel, an emblem of a land that maintains its beauty, strength, and dignity in the face of forces that threaten to tear it apart."
