One thing remains consistent for Virat. He always supports Pakhi when he is at loggerheads with Sai. Remember that Amey fight, he went screaming Pakhi...into her room.
When he makes up, he sees Pakhi through her manipulation/ games and starts ignoring her. Which is what he is doing now. Even ignoring the fact that she is suicidal.
Which is also why we are fed up with him😆. I don't want Sai to know he still loves her. the ball is in his court. Sai doesn't expect anything from him. It has been portrayed quite clearly by the actress.
This time, Sai needs his full support against his family, not because she is an abla naari or whatever😳. In fact it would a bonus if she gets the chance to move on.
For Virat, things are now slowly reaching a head where his entire family is watching this, just like the good old times before the leap. Now he has that much more of a duty to be faithful to one person. And logically it has to be Pakhi. As of now, he doesn't regret marrying Pakhi! Doesn't regret choosing Pakhi over Sai. Noone does. Not even BK as yet.
