I'm looking for a short science fiction story I read a long time ago. I don't remember the title, author, book, or anything else about it, except it was about a couple having an argument, and the woman left their house and was killed in a car accident. Throughout the story, things move backwards to the moment she left and the man stops her from leaving and she doesn't die.
It's all jumbled up in memory, because I read it so long ago, but if anyone knows what this story is or what it might be, that would be really helpful. I've been searching for it for ages and haven't been able to find anything about it. I think it began with the sentence, "The man undrank his drink," or something of that sort.
