I agree completely with you, my friend. This disappointment is what I didn't see coming. Till yesterday, he didn't really care what happened to Veer. He felt that his love for Mishti is above friendship with Veer. I am perfectly fine with that sentiment. It is not like he suddenly woke up and realized Veer is in the picture. He always knew Veer is in the picture and how Mishti is related to him.
I also agree that he has no business of telling Veer about his love. It is totally up to Mishti to tell Veer that they are incompatible. I am also OK if she didn't want to give Ruhaan as a reason, if she didn't talk it out with Ruhaan yet. But, but, as far as Ruhaan is concerned, he knows why Mishti would withdraw from the commitment, HIMSELF. What I don't get is why should he decide to leave AFTER knowing what Mishti felt for him and confessing to Mishti how he felt for her. He was restless to know her feeling towards him and once she reciprocates, he prioritizes everybody above her. That creates a disturbance in her life, doesn't it? What exactly does he want Mishti to do with this info? Does he expect her to carry on with Veer with the info that he loves her, and vice versa? How is that then right by his friend? If she is breaking up with Veer, then does he just expect her to rot away alone, pining for him for life? I really don't get it.
I don't know what the writers wanted. Didn't they think that this would come off as kaminapan on the part of Ruhaan? Did they just want Ruhaan to save face as a non- betrayer of a friendship? But this really doesn't serve that purpose too. The decent thing would have been for him to stay put as a support in case she needs it. It is totally up to her in how much she would disclose to Veer during the break up. This guy is now coming across as a coward👎🏼 I agree, if he comes back when the lines are all clear, then chappals toh bante hain.
