It was a rash decision at first but she did ask her parents to call off the wedding when Virat gave her the promise, he promised her because she was ending this wedding ceremony
If Virat wasn't going to marry her, he should have let her believe that he was a cheater, but he cleared her misunderstandings and then asked her to marry his brother when she was asking her parents to end it
Virat is not blameless here, he moved on quickly, broke the promise without a thought, but he didn’t understand that it wouldn't be same for the woman whose husband left her on day 1 and she is living with Virat 24/7
If Samrat was there or She was allowed to live with her family away from Virat, things would have been different for her
