What is the narrator point of view in the short-story collection, This Is How You Lose Her?

Because the book is a series of short stories, the point of view frequently changes. For the most part, all of the stories are told from the point of view of Yunior. The only exception is the fourth story which features Yasmin as the main character. Some of the stories are told directly from the first person perspective and are set in the present. Others are framed in the second person, with Yunior speaking to himself about what happened. These events are implied to be journal entries. Miss Lora is especially framed this way as each part of the story is numbered, implying they are being written down and listed in a journal.
