As if she is the only one tolerating n doing everything in this family.
I think the way she behaved with Kangna while leaving MAdhav to school and the precap, is what will tilt Ravish again towards Kangna. Cause no matter what Kangna did with Ravish, she deserve to be a part of Madhav's life. Vividha cant simply cut her off from his life like that.
This behavior is exactly what KK did with Vividha. So she is proving that she is his daughter only.
