That's exactly the point. How can she allow the decision of her marriage to her friends...she cant and she shouldnt . If she wanted that relationship then she should fight for it. Best example is Sameer and Naina , they want their relationship to survive...and their friends and relatives understood that...when the need to survive is more , people will understand...when did Swathi show that need, we have seen Munna blabbering about the relationship...if she went and did her engagement what will her friends do...did she tell them before that ...we have no clue..Swati did tell Kamya. It's Kamya and Preeti who have taken a decision to keep quiet. We don't know what exactly she said to Kamya, but we'll see...I hope. We don't know what she and Munna spoke about when she had asked to speak to Munna, she may therefore have told him about the proposal and Munna may not have given her the assurances she needed. Munna has however been neglecting Swati for a long time so it's very likely that Swati has realised that the relationship is going nowhere.
So either she is going to elope with Munna with their friends help or she is going to tell them that Munna isn't serious and she doesn't think this relationship to survive hence she has decided to move on...
When one needs anything in life ,not just about marriage...anything.. its the person who needs it should work hard to get it...only then people around will understand and try and help you in the best possible way they can. Never sit back and think it will be offered to them on a golden platter...
Even in Naina and Sameer's relationship there was phase when Naina decided to listen to her family and get married to another guy. At that time even Sameer couldn't do much as she was adamant that she will only listen to her parents...Only now Sameer and their friends could help because Naina herself decided to be with Sameer. A gentleman will never force his affection on a woman , she needs to make him feel that he matters to her and he is the one with whom she wants to spend her life.
They still have time , only engagement happened...we will need to wait and see what Swathi has to say ...
