Florence Grimes is the protagonist and point-of-view character in All the Other Mothers Hate Me. Florence is a complex character who, over the course of the narrative, transforms from a woman defined by her regrets and jealousies to someone who uses her agency to help others. She is characterized throughout by her desire to be an ideal mother to her 10-year-old son, Dylan. Although she tends toward immature, self-destructive behavior, she overcomes this to act to save her son.

Florence is a washed-up, former minor pop star who, as a teenager, performed in a British girl group called Girl’s Night. She is 31 years old and beautiful but reckless, argumentative, and immature. Florence is defined by her outsider status. She comes from a working-class American family and has found herself amid the wealthy, status-obsessed world of the London bourgeois. While the other mothers are rich, sexually conservative, and career-oriented, Florence is middle-class, sexually promiscuous, and has a job selling balloon arches. She has a chip on her shoulder about British class stratification and feels discontent with her life.

After a drunken hookup with her manager, Will, she becomes pregnant. Will marries her, only to leave her when their son, Dylan, is two months old, to marry her bandmate, Rose. After Florence has a public mental health crisis, Will relaunches the group without her “just in time for the first wave of millennial girl band nostalgia” (81). At the opening of the novel, a decade later, Florence is still struggling with her feelings of resentment, depression, and anger over her past. She’s embarrassed by her lack of success when compared to her former bandmates and resentful of their wealth and comfort.

Florence turns to self-destructive behavior to cope with negative emotions.. For example, when she runs into her former bandmate, Lacey, she feels overwhelmed and runs away to a bar to have anonymous sex in the pub bathroom. She remains furious with and heartbroken over her ex-husband, Will, for leaving her. When she thinks of his announcement that he is leaving her for Rose, and she notes that “even now, a decade on, I can barely recall those words without conjuring a flood of snotty tears” (81). After leaving the band, her music career has stalled. She has spent the intervening years raising her son and occasionally selling balloon arches on Instagram.

Florence has spent a decade frozen in place. As a young single mother overwhelmed by life, she has resisted maturation. Instead, she blows off steam by watching terrible reality television like Property Shark, having no-attachments sex, and relentlessly judging the wealthy women in her life, including her sister and the other moms at the exclusive St. Angeles school her son attends. She has no close friends.

The anchor of Florence’s life is her son, Dylan, introducing the novel’s thematic engagement with The Motherhood Ideal as a Source of Identity. For all of her anger and regrets, she readily admits that “Dylan is the best thing in my life, without exception” (81). Despite her personal limitations, she does her best to protect and care for him. She prepares him vegan meals, allows him to adopt a local box turtle, and worries that he is bullied in school. She recognizes that “Dylan has always been a bit unusual” and is willing to resort to violence as a result of “his absolute sense of right and wrong” (16). It is this understanding of her son that leads her to worry that he might be involved with Alfie’s disappearance.

Florence's motivation to protect Dylan from harm spurs her character development over the course of the narrative. Florence becomes suspicious of her son when she realizes that he was the last known person to see Alfie, and she finds Alfie’s backpack under his bed. Her concern for her son spurs her into direct action, a sharp contrast from the listless aimlessness that had characterized the past decade of her life. She actively begins to cultivate a close friendship with Jenny, both because of Jenny’s support for her investigation and because of the desire for connection. She finds her old patterns no longer serve her. For instance, she notes that watching Property Shark “isn’t having the same liquid-Ambien effect it usually does” (183), and she finds herself “disgusted” at the prospect of having sex with a married man, Matt B.

Florence’s character arc culminates in the final chapters of the novel when she races to Cornwall to save Dylan from Adam. On the journey, she confronts The Negative Personal Impacts of Regret and Jealousy, noting that her disparagement of the other mothers is “petty” and that some of them are “actually really nice” (318). She acts with bravery and determination to confront Adam. When she realizes that Adam has kidnapped Alfie, not Dylan, she acts with selflessness to save the boy, even though he is not her son. The narrative rewards her for this growth. By the end of the novel, Florence has a close friend, Jenny, and enough money to buy Adam’s apartment so she can provide a stable life for herself and her son.
