executive spinster
A successful, career-driven woman who refuses to settle for a man who (a) earns less than she does (b) her social circle/family would disprove of, and (c) someone she feels she can't look up to. Years later, she finds that by not compromising, she's in her 40s, single, and turns to artificial insemination as a last-ditch attempt at motherhood.
After vying to make partner at the firm for 16 years, Fran put off starting a family. By the time she made partner, she was 44, her looks had faded, and she was relegated to the role of executive spinster: take out Chinese, Grey's Anatomy, and 6am spin classes.
