Anu, what she could mean here u know...that once I make myself clear to him that I never meant any dhoka for him, prove my innocence then I will leave him. Babi was asking her to come with her rite away and on that naku meant "AAi not now...first let me prove my innocence and then i will leave him" and then wen she tries to leave him, its Dutta's call to stop her or to let her go...hope so me making some sense
