Encounter, a recent 2018 drama. This was more the backstory.
The fl married the 2ml way back when, but his family was toxic, so he divorced her for her own good. The marriage was arranged for political/business reasons. Fast forward a few years, the fl meets someone and is finally happy, then the 2ml realises he loves her, wants to get her back and fails miserably.
Not quite the same, but very similar.
