I dont understand why people are misunderstanding riddhima, some one says its jalousy while some one says its deep concern about armaan and few anti intelligent people says she is mother of armaan, i know she is very rude with shilpa and she had given her final judgement on shilpa without even knowing her but it doesnt mean she has became villan of dill mill gayye.
Jalousy
If she get jalouse of ArSh than what is wrong in it? She was in relationship with armaan since two and half years and every one knows that her love was not fake if armaan can get jalouse when he see sid and riddhima together so why cant riddhima? I mean now armaan has accepted the reality of siddhima's marriage but riddhima has seen ArSh together for the first time so its obvious that she will feel something. How much she says she has moved on even i agree she has moved on but it doesnt mean she has no feelings for armaan, if armaan has right to get jalouse than why not riddhima? but it doesnt mean she want to leave sid, even armaan was jalouse at begining but he dont mean to seperate sid and riddhima, its natural on which human has no control, these feelings comes automatically.
Deep Concern
Ya she is bit worried about armaan,because she dont want armaan to suffer from break up onse agin thats why she is tensed about him and she also dont know much about shilpa i am sure onse she come to her reality she will accept their relationship.
