Why Hrithik's sister is leaving home now?

It says that when one problem creeps in it makes way for another. The same is happening here in the Roshan family. Now that both Hrithik and Sussane have filed for the divorce, their separation is now inevitable. She is leaving separately with their sons since a long time now. Another member who has moved out of the Roshan home is Hrithik's sister Sunaina. She is said to be very attached to Sussanne. She herself had a not-very happy family life. Unfortunately her marriage did not work. It is said that she was very upset with the Hrithik-Sussain separation. Hrithik's maternal grandfather, a veteran filmmaker, has been a very family man and wanted everyone to live together. But unfortunately, Hrithik, Sussanne, Sunaina have all left the Roshan family.
