In the novel Of Mice and Men, Curley's wife does not relate well to the themes in the novel. She does not desire the lonely life she lives. She does not enjoy the isolation. She has always desired the more exciting life. She dreams of acting. She dwells on the past when she was observed by some who thought she could make it acting:
But she is pathetically lonely and once had dreams of being a movie star.
The ranch hands are gone all day working. They play games at night. Curley's wife feels left out. She obviously desires companionship. She has no interaction with society.
She lives out on the ranch, away from women her age. She is all alone on the ranch. She feels alienated from society. She has no one to confide in. She is basically without a friend.
For this reason, she reaches out to the field hands. She has no choice but to talk with Lennie. She uses him to get the attention she is so desperate for. Because she played with Lennie's emotions, she winds up with a broken neck. It was an accident.
