Peter and Alicia Florrick, The Good Wife
When the entire premise of your show is about a woman standing by her political husband despite a public sex scandal, you know the central relationship is in trouble. Alicia (Julianna Margulies) left her job as an attorney to be a good political wife to Peter (Chris Noth), and he repaid her by sleeping with prostitutes. Using state funds. The amazing part is that Alicia initially stuck by him after the story broke, to keep up appearances. It's just what every little girl dreams of: A broken marriage held together for the sake of the media.
