Unfortunately that is the state of affairs if someone else plays a role in your relationship with your spouse. If it goes well, everyone will be happy, but if something is not going right, then the third person will be the first one to be blamed by both husband and wife! That is OK, dhosthi mein yeh sab chaltha hain and I think Vikram/Neha will not be offended so much considering how happy RaYa will be with each other! That is the beauty of friendship!
That said, it is very good that atleast now RK has decided to take things in his own hands and he has to be man enough to accept his love for his wife!Cheers,Jay.
