So I don't know if I am the only one who sees this but I know Abhi hurt Akshara, he was unfair to her...and she went through a lot..
The way I see now is that the writers have been showing us that Akshara is happy and has a peaceful life while Abhi is suffering alot since he met her and her family and I think that for them is his redemption track...or a way to show that its tit for tat... because Akshara has no idea about the state of his mind....
From that mental breakdown ep...he has not fully recovered... and I really think that they are trying to show mental health issues... reason doesn't matter...but Abhi has completely lost it, I realized after today's episode. HE IS HALLUCINATING. Wo usske dimagh pe sawar hai...he is not himself. He was blubbering... with mental health issues, something that can be otherwise a tiny/small thing seem paramount and He is not able to do anything else because that thing has completely taken over his brain. You cannot control that.
Akshara suffered because of him and now it is his turn.... that is what is being shown....in a way that seems obsession and Abhinav said that today...about being free in love and not bounding anyone but Abhi is not able to think or reason with anything.
He has completely lost it and I see it as Usske paapon ki saza.
He has done so much wrong that all this suffering came his way... but maybe I am the only one who can perceive this.
