Example:
Aarti allowing Prashant in SM and then apologizing for her behaviour was not realistic. Keeping Prashant in his place was not wrong on Aarti's part, in fact she should have never allowed him in the house.
Prashant with Aarti to drop Ansh is also not realistic. Allowing him to go is against her character and sitting together with him in the front seat is certainly against her character, especially after her interfered between her and Yash.
CV's seem to be trying best to ruin the show. In the current situation I think it's not possible for Aarti to earn trust again, either from Yash or his family and they won't be totally wrong. She has lied and deceived too much and even though she didn't mean to hurt them she has done that over and over. Marriage can't survive without trust and Aarti has broken trust too many times.
I will wait to see how the CV's will explain Aarti's forgiveness. I doubt the track they come up with will be convincing but I'll wait to see.
