My heart broke for Virat today. I understood 100% where his insecurities are coming from.
He is a man completely in love. It doesn't matter what his age is, what his profession is, or how settled he is. Love overpowers all rationality and other emotions.
Even though he can see that Sai is falling in love with him through certain actions of her's, he is getting no reassurance from her. Every time he tries to do something for her, she brings up the vaada and the zimidari. And I understand where she is coming from in this regard, too, as I have written in numerous other posts. But, focusing on Virat here. He is scared of losing her. He is scared that she will never accept this relationship as real. He is scared that he is too old for her and that she will find someone she is more compatible with.. and the manifestation of that is Ajinkya. And, I understand why the age thing is bothering him. Sai's intentions are pure when joking about it, but from his perspective, he is already insecure about this, and Sai keeps on tugging at it. Bringing up an insecurity over and over again is more than enough for someone to get pushed over the edge about it.
He sees the way that Sai looks at him, and she even expressed how much she admired, respected, and was thankful to him today. Despite all of this, he is getting no verbal affirmations of this relationship from her... just like she isn't getting any verbal affirmations that clearly are allowing her to move on from the vaada just like he is. Both of them are stuck in similar positions in this way, and that is why to me, both of their insecurities are heartbreaking.
