SOLVED. Book about a woman who you think is obsessed with her ex-husband's new wife [s]

[Alexandria]

I read this book earlier this year and I’m pretty sure it was published in 2017 or 2016. You think you are reading about a woman stalking her ex-husbands new GF but then you find out your not. The woman in the book was a preschool teacher. The book cover has two blonde woman on it and it’s purple and the words are yellow. The title is similar to “the other wife”, “my husbands wife” or “the other woman” I can’t for the life of me find this book to recommend!
