I find her grief natural and apt for what she has gone through. It's obvious from her lines to anurag that she hated him make her beg and mocking her love. The fact that it hit her to the core shows how deep her love for anurag was and is. And I'm glad they showed this phase if prerna.
I really want anurag to stand up for himself. What do you want in life anurag? Is it prerna? If so, go for it. If it's Komolika then go for that. If it's neither then that. Or maybe it's your mom who is the most important person in your life... that's fine too. But this inability to commit to anything with full force and conviction and stand by it. Maybe it is just me... but I can't stand this dilly dallying. I don't know if that makes me too demanding if anurag or seeing faults where none exist. Or as someone said - making him a damned if he does and damned if he doesn't. I would find it so confusing to date a guy like anurag - I wouldn't know where I stand on any given day. If you promise someone something, then keep your promise. Call your sister to help your mom and help her girl who is in that state because of you. YOU.
Now coming back to prerna. Unlike I think everyone else I DONT want her to go to Basu mansion. I loved the grief, I loved the desperation- because it's natural. But then I want her to just try to get on with her life. I would have preferred her to call anurag while he is on his reception to say I am pregnant. I want nothing to do with you but I am informing you as it's the right thing to do. And for anurag to then coming running behind her. I know it's the boring options ... but I am going to hate every moment of this Basu drama where everyone will insult prerna.
