As far as her affection or pain for Armaan is concerned...Isn't thta normal?? Riddhima knows very well that Armaan is suffering on her account...So she deeply regrets that...She knows Armaan so well...She knows he will hurt himself...Thats why she wants to keep an eye on him..But at the end of the day, her happiness and her world is Siddhant and that's her own choice..No obligation....
See this video...http://www.youtube.com/watch?v=tSKGmPruoiQ...You will know whether its a compromise or choice....I agree Riddhima and Armaan are more than 'just friends' and they will always have a soft corner for each other...A complex relation ship...Of deep care, concern, affection... Something between ordinary friendship and love...Its always gonna be a special relationship...
