Yes couldn't have said it better, the more he loves the more he is going to get desperate. We see that with his job he can't bear to lose something else in his life that he holds dear. But what he doesn't realize is Paro is overtaking his BSD obsession, she will definitely consume him to an extent that nothing else with matter. He is a man of singular obsessions. First his mother, then his job, now it is becoming Paro. He is not good at multitasking his emotions that is what makes Rudra volatile and off the edge type character, he is used to channeling his energy on one thing as a therapeutic process for dealing with pain. That will be his journey to learn to balance his life, to learn to accept loss, not let the fear of loss overwhelm him because loss is a part of life it doesn't have to define you, learn to be happy, but not let obsession overwhelm his happiness. He is a man of extremes needs to learn to find the middle ground.
I think Paro needs to tone down on the name calling. Why did she have to call Rudra Jallad when he asked her to stop singing. He was genuinely upset and freaking out it had nothing do with her specially. It came off unfeeling on her part to call him cruel over something that was giving him so much pain. It is not like he asked her to stop singing and stormed off he took the time to tell her it was hurting him he shared his reason with her it was his past. Paro has already apologized to him for using his mother to hurt him, so here he is telling her the song reminds him of the painful past she should have known painful past means memory of his mother and she just crossed the line so she should have been considerate of that.
Another thing I love about this episode is how it is officially Paro now for Rudra. He doesn't call her Parvati even to a third person that would be the formal way to address her. He has definitely jumped some steps, first from woh ladki to now Paro. Aman has been addressing her as Parvati and it doesn't irk Rudra, there was a time when he forbade Aman from giving her such respect to a criminal then. Writers have done a good job in bringing this change it wasn't too sudden woven in the story well enough to justify how Rudra has accepted her as his. I hope everyone in the show address her as Parvati, and she is exclusively Paro for Rudra. With the name he has signaled the status of their relationship she is his girl.
