In Arthur Miller's Death of a Salesman, Linda, Willy's wife, is very supportive of her husband.
Linda is Willy's long-suffering, devoted wife, who desperately loves her husband...
When Willy brings home news from the job, Linda listens very intently. In fact, when he speaks to her, her attention is only for him. She gets excited about the things that excite him. When he comes home from a sales trip and tells her stories of how successful he has been, Linda has nothing but praise and admiration for him.
…[She] continuously presents a cheerful, hopeful appearance...
In other words, regardless of what Willy says or does, Linda is his constant support, and she never stops believing in him—she sees only the good. Linda tells Willy he is good-looking and loved by his sons. She says:
Willy, darling, you're the handsomest man in the world—
Few men are idolized by their children the way you are.
Linda makes the things important in her husband's life, important to her. If he experiences self-doubt, she encourages him. In showing him how strong she believes in him, Linda wants Willy to also believe strongly in himself. These things show how much Linda loves her husband.
