Suggest me a book for a breakup

Hi. I (mid 20s F) recently broke up with my boyfriend (late 20s male) of 4.5 years. I wasn’t feeling seen or like he was putting in much effort. Also, I wanted to be independent and on my own. I am not looking for self help books. I’m into classics, literary fiction, female rage/books where it’s mainly ab women. I’m not really looking for romance. In fact, please don’t recommend a romance novel. Maybe ab independent women. Idk. I’m not the best at articulating my thoughts lately.
