Mildred is the one major character in the book who seems to have no hope of resolving the conflicts that she is facing. Her suicide attempts means that she is in great pain and that her obsession with television is a means to avoid confronting her miserable life. She is also distant to the reality around her, including her husband.
As Montag tries to talk to Mildred throughout the book, her responses are bland like she doesn't care about what is happening around her. She lives a robotic lifestyle like everyone else, surrounding herself with friends to fill in her emptiness.
As Mildred continues her "fake" life as a wife, until the point where she betrays Montag by turning him in to Captain Beatty. SHe walks away from their marriage like nothing, showing the little importance Mildred gives to family. Instead she cries over something that isn't real, which is her TV "family."
