The central marriage in A Streetcar Named Desire operates on a tumultuous combination of hero-worship, aggression, sexual attraction, and a difficult class difference between husband and wife. Despite the challenges, we never doubt for a moment the intensity of love these two feel for each other. There’s something primitive or almost animal in the ferocity of their interactions – both fighting and love-making – that makes their relationship difficult for some other characters to understand. In this marriage, we definitely see traditional gender roles of a dominant husband who brings home the money and pays the bills; and the doting housewife who is responsible for making dinner, cleaning up, and raising a child.
There are no positive relationships between men and women in A Streetcar Named Desire.
