Karan does not respect his wife and ANYONE who doesn't respect his wife is the worse person living on this earth.
Tanya did EVERYTHING for this family and Karan, and what she gets in return NOTHING. Tanya did everything right and fulfill ALL her promises. She married Karan only after Karan was willing to accept her as his wife and only after they found out that Nandini would never come back.
Karan used her for all what he wanted, have kids with her and then one day he goes "oh I want Nandini back… "
He insults Tanya in everyway possible and Tanya who has FULL rights as been his wife says nothing, and even now as promise she is willing to walk away from Krans life for Nandini. What a great lady Tanya is.
So ladies and gentlemen, Karan is cheap, Karan is a player, Karan has no self respect, Karan can not keep the family together.
Tanya you are just GREAT!!!!!!!!!!
