Seven Exes by Lucy Vine

The story follows Esther, a thirty-something woman who finds herself thoroughly exhausted by the nightmare of modern dating apps. While clearing out her old room, she comes across an old magazine article that outlines the "seven types of exes" everyone has before finding true love—including The First Love, The One That Got Away, and The Mistake.

Convinced that she must have already met her soulmate and somehow let him slip through her fingers, Esther decides to tracking down her own seven ex-boyfriends. With the help of her ride-or-die best friends, she embarks on a nostalgic, often cringeworthy, and hilarious journey to see if any of them deserve a second chance.
