Another way to look at it is Ammu always gets betrayed by the ones she trusts / loves... and perhaps cant hate them even after that - (arguably Shubh in the past), her dad, Virat, and likely going forward her mom.
Another angle: JK... any normal person would probably try to talk to VA about the developments and plans. But she... nope. she will be countering the moves by shipping VA. probably Bhavani will make her promise too - so promise becomes more important than a couple's "marriage" (even if it be so called marriage).
