Fleishman Is in Trouble: A Novel by Taffy Brodesser-Akner:
Toby searched his bleary brain for their last hateful interaction and remembered it with the force of a sudden, deep dread: Rachel had been sputtering some nonsense about opening up a West Coast office of her agency, because she was not busy enough and overwhelmed enough as it was. Honestly, it was a blur. She’d ended the conversation, he remembered now, by screaming at him through her sobbing so that he couldn’t understand her until finally the line went dead and he knew she’d hung up on him. This was how conversations ended now, rather than with the inertia of marital apology. Toby had been told all his life that being in love means never having to say you’re sorry. But no, it was actually being divorced that meant never having to say you’re sorry.
