My Love-Brain Is Cured, Now Please Let Me Go!

I’m a Sucker for the Groveling-after-the-breakup Trope. I Just Love Watching Them Win Their Exes Back

High-Quality Novels Where the Male Lead Has to Beg for His Wife Back

Are there any high-quality groveling-after-the-breakup novels? In some of the ones I've read, the heroine is such a pushover and the hero is an idiot. Please help a friend who's in a reading slump!

He Gets His Kicks from Tormenting His Wife, Then Has to Beg for Her Back. Completed

The arrogant CEO is satisfying for a while, but once he comes to his senses, the heroine wants nothing to do with him. After they break up, all her secret identities come to light.

The Male Lead Regrets Losing Her and Tries to Win Her Back (With a Little Angst)

At first, the male lead treats the heroine as his mistress, and she knows where she stands and behaves herself. She gets jealous, but keeps it to herself. Then his first love returns, and the heroine leaves on her own. The male lead realizes he's already fallen for her, and then comes the desperate pursuit to win her back.

The Ex Chases After Her

Groveling-to-win-her-back stories!!! The kind where the male lead gets put through hell later on! The more painful, the better.

The Ex-Wife's Redemption Arc

I'm fine with or without a couple pairing. The man mistreats the woman early on, then regrets it and tries to win her back later, only to find he can never get her back. I don't like stories where a woman gets horribly mistreated but still lets the man win her back.
