For the same plot but with the MC who choose to take revenge on the ex instead, I don't have anything in mind. But for great love story with second chance reincarnation or transmigration, there is actually a lot.
Death is the only ending for the Villainess
The Villainess turn the hourglass
The Villainess Lives Twice
Please throw me away
Common sense's for a Duke's daughter
Empress of Another world.
For completely different plot but still masterpieces:
Spice and Wolf
Light and shadow (except for the 4 first chapters. We don't talk about these. The rest of the story is great however)
Kusuriya no hitorigoto.
Funny enough, for the twists of the "return with the abuser" trope that i can think of are from chineses novels. "Beauty and the beast (not sure about the title) for instance is a story in wich the abuser is the one who is send back in time (the victime do regain her memories toward the middle of the novel however).

The blue haired entitled prince from "The Abandoned Empress" or this black haired whiny Emperor "Lady To Queen"? They are both stupid royal brats craving for confirmation.
It is very frustrating to see a strong willed capable FL trying very hard to overcome her trauma and any obstacles in her life only ending up falling for her arrogant biased childish murderer (again)!!!!
There are other novels (search in NovelUpdate) with similar plots - ML kills FL + She keeps suffering until he is reformed/perfect.
Here are one of the most used absurd excuses for the ML:
Missunderstood, Abused, Cursed, Drugged, Manipulated, Brainwashed or Forced by other political circumstances.
So once the FL starts to emancipate herself, the ML who caused her pain and death becomes somehow interested in her and pursues her until she is wore down/touched by his persistence + charm.
What kind of fucked up message is that?!
