I think Sai is doing her best to balance the clowns vs those who are supporting/caring for her. She is showing her growth. She is making her points without getting brash like she did when she was new to CN because she knows its a vicious cycle. She is not the same Sai because the situation isn't the same. She did love Virat even if she didn't admit it, she values his contribution in her life and now shes a broken/cheated person. Unfortunately shes not even in a position to ask him - if you loved me why did you do this because she thinks her responsibility is what prevented him for having his own smaller "family". She has no idea how to react. Her oen marriage was unusual n she didn't know where they stood so unlike family, Sai is not as "outraged" because she has this drilled into her that she is tough to live with n love. How can she be the same Sai after singlehandedly tolerating so much... She does leave the house because no matter what - she has no business staying longterm there. She however has a special connect with them. For a girl who never knew family and lost her only family, she genuinely thinks of everyone in CN as her family. She genuinely accepted them as they are because Virat asked her to do so n because atleast the important people- like Virats parents did come around n accept her - especially ninad. Today Ninad repenting how he used to treat her in early days is a good touch. He sees how Sai's life in CN is a series of difficulties/insults even though she did her best to do good to everyone. And as older, mature people it was their responsibility to cut her slack because bacchi hai,nayi hai but ulta they tortured her n Sai was the one to treat everyday as a new day.
