Hey, anyone else feel like that's a very specific itch to scratch? I love seeing these super direct search queries bubble up in forums—it tells you exactly what mood someone's in. So, diving right in: yes, this exists, but the exact phrase 'throw away the cheating husband' as a title might be a Chinese web novel translation. You're probably looking for something like 'The CEO's Wife Files for Divorce After Rebirth' or 'After the Divorce, I Became a Billionaire'—those revenge-on-cheating-husband tropes are huge in the 'CEO contract marriage' or 'reborn' genres.
For free official translations, your best shot is platforms like Webnovel or Goodnovel. They have a ton of these stories, and many offer the first 50-100 chapters free to hook you, then switch to a coin/unlock system or a subscription. I've been burned before downloading from random aggregator sites that had terrible machine translations; the official ones are way smoother to read, even if they're slower to update.
A word of caution, though—sometimes the 'official' translation might only be for the first book in a series, or it's completed but locked behind a paywall after chapter 20. I usually read the free samples, then decide if it's worth using my daily passes or waiting for a platform promotion. The update frequency on these can be brutal if it's ongoing, so I tend to hunt for completed ones when I'm in a binge mood.
Ending thought: the legal reading route is definitely less frustrating in the long run, even if it means waiting a day for a free unlock. The grammar errors on shady sites just kill the cathartic vibe of watching the trash husband get dumped.
