Unpopular Opinion: Heer and Nawab’s "crux" is entirely gone, and they shouldn't be endgame.
Despite their differences, the protagonists of any fiction,be it a show or a novel,should share a fundamental crux, a core bond that ultimately connects them. Unfortunately, Heer and Nawab no longer have that.
Heer has developed a deep sense of entitlement when it comes to Nawab. She constantly tries to "play God" with his life while simultaneously blaming him for everything that goes wrong in her own. Meanwhile, she gives Arjun an immense amount of undue importance. She is overly invested in making her engagement and subsequent relationship with Arjun work, pouring far too much care into a dynamic that clearly isn't right.
On the other side, Nawab has finally reached his limit after making countless, exhausting efforts. He has chosen to give up and move on, and the makers are also portraying Simran as the perfect balm for his wounds. Narrative clearly suggests that Simran provides the genuine support and care that Heer’s character sadly lacked after a certain point of time and sadly it continues till now.
Most importantly, the narrative also highlights Nawab’s growing comfort and affection for Simran. Around Heer, Nawab’s nerves were always tensed, as if he constantly had to prove his worth. With Simran, he finally experiences a sense of lightness and ease.
If I was a writer, I would have never bought Heer and Nawab back together.
As per the current narrative, and the whole show is gone after a certain point, the most possible and edible outcome would be:
For Nawab: Simran is currently the healthiest choice. She offers him the peace and appreciation he has earned.
For Heer: She needs to step away from romance entirely to focus on her individual growth. She must break off her engagement with Arjun, free herself from these toxic cycles, and learn to stand on her own two feet.
Ultimately, Heer deserves a balanced relationship too where she neither constantly blames her partner nor faces constant blame herself. But a healthy, mutual love like that is simply impossible with either Nawab (first case applies) or Arjun (second case applies)
It is better this way.
