About Rudra:
I think his past relationship was a passionate relationship full of sparks. It's going the same way with Maya. Once a person has got a taste of a passionate roller coaster relationship, he subconsciously gets attracted to same kinds of feelings. That feeling is often like alcohol, you know it could harm but still you get dragged into it. But the problem with that kind of relationship is, often that spark becomes a hellfire and burns the person alive. That's what happened to Rudra in the past.
Today when Maya didn't open the door, what Rudra felt was a second glimpse of that hellfire which he tried to forget for so long. It felt like a volcano awakening again and he ran for a comfort shelter. A cold safe place where there is no spark, no emotional roller coaster and no unpredictability-----just a calm, old, light and breezy comfort zone. And that's what Ananya is to him.
He is feeling like ---- enough with the passion, enough with the confusion, enough with the pain, not everyone is made for a relationship like that and he is certainly not lucky enough ! And that's why he ran back to the comfort zone and he has currently no intention of getting out of it ever. And as Maya didn't open the door, he thinks his feelings are one sided, or worse Maya is just making fun of his feelings and playing some game. So he doesn't have any expectations of Maya coming in his life and that's why no reason to leave Ananya. So in his mind, he is making a logical decision. But he has doubts and he tried to share it with his best friend. But his best friend was too busy in her denial zone to listen to his words.
About Ananya:
I think she knew in her heart that if she had listened to Rudra's past and reasoning, both of them would arrive to their right senses and her little bubble would burst. Right now she is on top of that swing which Rudra mentioned. She subconsciously knows she will be in the ground in no time. But for now she just wants to enjoy the top view she had been waiting to reach for so long. But once she is out of her denial, I hope she gains back the maturity and practicality we loved in her character.
I hated the Mayazaal pinch. As if her feelings are serious feelings, but Rudra's feelings are dumb infatuation and has only succumbed to Maya's seduction. Which is true for Rishi. But I didn't like that pinch on Rudra, specially from Ananya.
