Armaan is amazing. No one can question the love he has for Riddhima. But all of a sudden he has become insensitive to her feelings. It almost seems like he wants her to react to the things he is doing. He doesn't wish to be the Z in her life. He wants to mean more to her. He wants to be the bighearted guy but he wants to be the guy holding Riddhima not Sid.
For me respect means everything in life. I couldn't be with a guy who disrespects me. Riddhima is not trying to run Armaan's life. he is not obligated to listen to her. But as a friend she has her share of rights on him. The same rights he had when he tried to play cupid between Siddhima. He is purposely hurting himself and Riddhima. It's disrespectful. Specially because it's another way of telling her you did this to me.
I would never think of comparing Sid and Armaan's love. Because Armaan has loved her longer. He knows things about her that no one else knows. But now Sid understands her better. Of course tomorrow it could all change but for the time being Sid understand her every single emotion. Sid respects her privacy. If Sid wanted he could exercise his marital rights. But he chooses to show her that respect. He listens to her. Lends her the ear to vent, provides the shoulder for her to cry on. He carries her through her troubles. He watches over her like an guardian angel. He understands her frustration with Armaan's situation. He even helps her with it. I admire the love he has for her.
Because Armaan is older and has been through more I expect him to be more mature. I expect him to understand Riddhima. it's amazing to see Sid. He is not Armaan but he is totally magical in his own way. He manages to do things I wouldn't expect him too.
