Maan : "Jab tum kisi cheez ki liye rhutke inkar karte ho toh..."
Geet : "Toh?"
Maan : "Toh dil ki aur kareeb ajati ho"
I'm sure the meaning behind it very obvious, but let me explain in case you did not understand it.
Every time Maan and Geet get into an argument, they get back together more closer than before. Every fiasco that has ever happened has brought them together on a more deeper level than the last. I'm sure you know what situations I'm speaking of, but here is an example; Maan and Geet argue because Maan is too possessive. What happens after that argument? We get "Roop tere mastana" sequence. Even Maan knows this fact about their relationship, so why don't you guys? You see the entire picture don't you? On Friday's episode they had the biggest fight and when they get back together they will reunite more stronger than ever.
And please stop playing the blame game. Maan and Geet were both wrong in the situation. Maan is not perfect, he was extremely rude and condescending to Geet. Geet is a naive 18 year old who has taken too much for anyone her age to bear.
