I think that jassi should end up with Armaan..after all they both deserve each other. She and Armaan both are good at breaking hearts. Both can not be trusted. Both treat others as no one matters except for them. Both think that the whole world revolves around them.
So my conclusion is that Armaan and Jassi should get married..after all they both have alot in common. I don't understand why Purab and Mallika want to be with these two..knowing they'll never be happy with them because both(Armaan, Jassi) are good liars and keep hurting these two.
I myself can't believe it but I think I agree with everyhting you just said.. they deserve each other..
