Comeon babi baby, she saw sid roaming around her even after moving on with aanya( as she knows this only). How can she trust sid when his own mother said that he had moved on and her return is effecting him. She learnt to trust mothers only after sid entering her life. How will she know that a mother can stoop so low that she made her son characterless by saying that her husband had moved on and that girl is carrying his child. She never thinks a mother can do it.
She returned after 2 yrs that to unintensionally. Aur insaniyat. She doesnt know that nd and neil has raaz now. She doesnt know even aanyas truth. She doesnt know that all people aroynd her are playing with her, but she is feeling that she is responsible for miseries in all their lives including sid life is in misery bcoz of her. She never asked sid to solve any of her problems na sid himself is doing remembering his vaada.
Nothing can be done until truth comesout in front of both sid & roshni.
Now roshni is just moving on with the flow. She will do all what can make her relation work . she doent evem bother weather she is happy with it or not.
Iam not saying that she is not at fault but not completely.
