You might like 'Love's Farewell'. It explores the complexity of love coming to an end and the aftermath, much like the book you mentioned. The characters' inner struggles and growth are comparable.
I'd recommend 'The End of Our Story'. It has a similar tone and approach to depicting the conclusion of a love story, with relatable emotions and circumstances.
Try 'The Final Farewell' - it has similar elements of heartbreak and closure as 'How to End a Love Story'. The plot and character development are quite engaging.
Wuthering Heights by Emily Bronte has a very intense love story. Catherine and Heathcliff's love is wild, passionate, and ultimately tragic. It's a story of love that defies social norms and has a dark, brooding atmosphere.
Some books like 'OCD Love Story' are 'I'll Give You the Sun' by Jandy Nelson. It's a story about family, love, and art, with characters who have their own emotional baggage. 'We Are Okay' is also similar as it delves into the main character's past, her relationships, and her process of coming to terms with things. And 'The Hate U Give' while more focused on social issues also has a love story aspect within it and characters with complex emotions.
One book similar to 'Twilight' is 'The Vampire Diaries' series. It also involves vampires and a love story. There's the complex relationship between Elena and the Salvatore brothers, Stefan and Damon. The supernatural elements, like vampires, witches, and werewolves, add an exciting backdrop to the love triangle, much like in 'Twilight'.
One book that might be similar is 'Eleanor & Park' by Rainbow Rowell. It also deals with complex relationships and the inner workings of the characters' minds. Another could be 'The Fault in Our Stars' by John Green. It has a unique love story and delves into the characters' emotional and mental states. Also, 'Fangirl' by Rainbow Rowell has elements of a coming - of - age love story with a focus on the main character's idiosyncrasies.
One example is 'The Jungle Book'. It is a collection of stories about Mowgli and his adventures in the jungle, and it ends with various tales that teach valuable lessons.
Don't make it too rushed. Take the time to develop the resolution and show the characters' growth and acceptance. Also, avoid a forced happy ending if it doesn't fit the story's tone.
I recommend 'The Godly Doctor's Dainty Wife Is Savage' to you. This novel was a modern romance about a wealthy family. The male protagonist was paralyzed, and the female protagonist was a divine doctor who treated him and helped him start a company. At the same time, the male protagonist's business empire became a battlefield for the two of them. I hope you like my recommendation. Muah!
One book could be 'Atonement' by Ian McEwan. It has a love story that takes a tragic turn towards the end. The misunderstandings and the consequences of false accusations lead to a love that is ultimately unfulfilled in a very heart - wrenching way.
'Wicked Lovely' by Melissa Marr has elements of forbidden love. Aislinn, a mortal girl, is attracted to Keenan, the Summer King, who is not of her world. Their love is complicated by the rules of the faerie world. It's like 'Twilight' where the different natures of Bella and Edward make their relationship difficult and forbidden in a way.
