Come on, that was only a dialogue, you get all sort of weired ones in Indian movies. Personally i would never marry a girl who decides to leave her house for me, i would never encourage the girl to leave her house in the first place.
I think struggle for their children all their lives and they have every right to choose a life partner for the chikdren, they always want the best for you and i would NEVER marry a girl who decides to leave her house.
