Linda is a woman in an awkward situation. She knows that Willy is suicidal, irrational, and difficult to deal with; however, she goes along with Willy's fantasies in order to protect him from the criticism of others, as well as his own self-criticism. Linda is Willy's champion. She gently prods him when it comes to paying the bills and communicating with Biff, and she does not lose her temper when he becomes irate. Linda knows that Willy is secretly borrowing money from Charley to pay the life insurance and other bills. She has discovered the rubber hose behind the heater and lives in fear that Willy will try to asphyxiate himself. She is also aware that he has attempted to kill himself several times before. Despite all this, Linda does nothing, afraid to aggravate Willy's fragile mental condition. In fact, she even throws Biff and Happy out when their behavior threatens to upset Willy. In many ways Willy is like a small child, and Linda is like a mother who anxiously protects him from Biff, Happy, and the rest of the world.
Linda is a character driven by desperation and fear. Even though Willy is often rude to her and there is the possibility that Linda suspects Willy may have had an affair, she protects him at all costs. According to Linda, Willy is "only a little boat looking for a harbor." She loves Willy, and more importantly, she accepts all of his shortcomings. She would rather play along with his fantasies of grandeur, or the simple ones like building a garden and growing fresh vegetables, than face the possibility of losing him.
