Yaar Virat will not ask Sai to leave him. That is not him. Even in KD till the end, he never asked Emon to leave him. He just does things on his own and expects her to understand.
So yeah, they might fight like enemies but wont go till divorce. In the end also, they separate but not take divorce I guess, in KD.
So dont panic. Looks like Virat lost complete trust from the audience.
After surrogacy kaand, I also did lose trust on him but his character is not the one to leave Sai as per original.
Msin can correct me.
