his swinging between vahini and biwi, is merely cuz of 'dragging drama' reasons of CVs, it is unrealistic and illogical.
it definitely is late to tell her anything, its just that ACP sir thinks that everyone does telepathy with him and thinks that his telepathic connection between him and pakhi is very strong so without telling it in verbally he directly went into thinking that pakhi knows it already that there is nothing between them..lol
about sai feeling humiliated it definitely is humiliating to her. like she said in yesterday's episode 'meri jagah koyi aur ladki hoti tho apni kismat pe rothi'. even if shaadi is a deal or real when two people enter into pati patni waala tag, knowing that his/her partner loves somebody else but he/she is with you only cuz of some majboori, is the worst feeling one goes through. this is the main reason that made virat also insecure when sai spoke to amey and made friends with aniket even though he surely was not in love with her by then.
yeha tho sai goes through that feeling everyday and sees and bears that lady she thinks her husband loves everyday poking her nose, tongue and everything into their matters.
