No there's nothing wrong here because these are not normal circumstances. It's not a situation where anurag has married someone else in sound mind and body and prerna has to accept it and move on. Anurag was not in his right mind when he married sonalika, in the sense that he had forgotten that he already had ties in his life (a woman he was going to marry and a child on the way). So there's nothing wrong in hoping and wanting that he gets his memory back and then they take it from there, whichever direction that is. . As for so called ghar of sonalika, well, prerna herself is a divorcee and knows how soul shattering it can be to be stuck in a loveless marriage out of compulsion. . If anything, it's prerna's generosity and niceness because of which she has till date not told sonalika about her relationship with anurag and their baby to be. Hiding it from anurag is one thing, but prerna could've very well told sonalika to get her out of the way. For all she knows, sonalika is a nice person who saved anurag's life and he in turn married her to save her. That's it! Its not like sonalika and anurag knew each other and wanted to get married. But she did nothing like that and instead, kept her distance. It's completely in order to hope anurag gets his memory back and they take a decision of their life. If he decides to stay in his marriage to sonalika, then she will definitely accept it.
as per you nothing is wrong , but she is decorating Suhag Rat room, that means Anulika is going to consummate together as per the current situation . and even anurag prerna ke samne saf saf mana nei kia , not even made clear that he will not stay in this room , his stands already made clear anurag he is going to stay with komo tonight.. ghar mai rat ko keya hoga woh alag bat. pre ko nei pata..
that means kisi aur ki suhag rat ki ghar mai khade hoke she is ok with anurag's physical relationship with his wife.. aur udhar khade khade prerna is thinking , after memory regaining , she will get anurag again ... toh sonalika ki keya? as prerna selfless hai , she is promoting the torchbearer of every good qualities toh kaise she is thinking about a married person ? agar sona inhi beech pregu ho jate hai tab prerna ka keya iyeahi stand hogi ? love ka keya ?
agar iyea thoughts woh kal komo ki expose ke badd deti , mai totally would ok ... but nah , not today ..
as a positive soul , as a positive lead she should not think this type of thoughts standing in some lady's SR where her BF is going to consummate with his married wife .. ( As per current situtaion infront of Prerna ) .. toh mere liye iyea morally degradation hayi prerna ki ...
