This may sound weird and I might not be able to explain myself.But somehow over the last few weeks, I have come to accept Armaan and Tanisha's weird relationship. I just know she's going to go back and he's going to do either his aapko jo karna hai kijiye aur main aapse door rahoonga or his bholenath ki qasam mera woh matlab naheen tha and then they will be "together" again.In a way, it's not similar to regular domestic abuse. Tanisha is too "smug" in herself. I think she just looks at it as Armaan's loveable quirk or something...I said I wouldn't be able to explain it...
Armaan hurt Tani physically/mentally/emotionally many times and apologised to her same number of times. Tani forgave him each and every time and gets back to him.
The point is when you say SORRY it does mean that you will not repeat such a behaviour.
I don't know Armaan's meaning of sorry. ( may be its like saying be prepared for next round)
