A tension that runs through multiple canon pairings is the conflict between career ambitions and family life.
Harry’s greatest desire is for family, yet both he and Ginny end up in demanding careers — he as an Auror, she as a professional Quidditch player and then correspondent. The secular norm says of course Ginny had to achieve all of her dreams without compromise. But Harry’s deepest need is not for professional achievement; it is for the family he never had. Someone had to compromise, and the books never address who or how.
Hannah Abbott faces a version of the same question. She was apparently a successful landlady at the Leaky Cauldron, but may be giving that up to become matron at Hogwarts — seemingly to be near Neville. Was this a welcome change or a sacrifice? The fact that we learn this through Rita Skeeter’s pen makes it impossible to know the tone of the decision.
Hermione’s career at the Ministry and Ron’s trajectory from Auror to joke shop add another dimension. Hermione is clearly the more career-driven of the two, and Ron’s apparent lack of ambition is part of what makes their pairing so fraught.
The wizarding world seems to have no concept of parental leave, flexible work, or any of the structures that mundane society has (imperfectly) developed to manage this tension. Mrs. Rowling gives her characters demanding careers and children without ever addressing how they manage both.
