well..i dont know..i mean, i didnt go through that huge argument with my loved one... so i wont really b able to tell how i would feel and all....but in my opinion, i dont think a HUGE change is right...i mean, yes, armaan would change himself around...but not in such a big way....
but then ,looking at it in a diff. point of view..i think it was something completely helpless and armaan could never control the way he changes his character. i mean, he's been in a lot of relationships b4...and, as far as i know, this one with ridz was his very first serious long-term relationship....so i think it is justified that when the two had a big problem and argument between the two, he returned to his old self...maybe he thought that he should never have changed from his old self..and that trying to become a good human being and not a player was not a good idea...that things never work out right with him and he was really stressed out...
that all really contributes a lot to the personality change..how armaan changed, it is justified in a way.
