I haven't watched the epi as yet, but reading the updates is very scary. I don't like that they fight so much even now. And I know I keep repeating myself, but I think Nandu needs to be a little more considerate towards Manik. She keeps pushing him away every time and he is so confused with this kind of attitude from her. Because of that he takes it all lightly and feels Nandini is playing him (remember his dialogue once with Cabir, saying I am playing along or 'maybe I am being played').
Nandini gives him mixed signals and that is not good for their relationship as he has already gone through this once when she said they could not be together. If Nandu really loves and cares for him, she should give him some reassurance that she is his and there for him instead of running away all the time.
