These all have a similar premise, I don't remember the exact details though so I don't know if they fit:

it's a historical manhwa, the female lead's husband is cheating on her with her best friend or something, they make her life miserable and the husband finally kills her and then she is reincarnated 7 years back and gets her revenge or
something
please anyone, if you know the right one, please do tell or anything familiar (historical genre) that would be nice too thanks
