@LM I perfectly understood your point of view, but don't you think she had two options available, either to go left or right.She chose to go Right (literally) .Now by every step she is taking in right direction,by same pace she is going away from left one.
Again is it not like sailing on two boats at a time?For the sake of her safety (emotional),she has to dismiss (totally) either.
I have never worn Meghana's exact shoes so I don't know how I would have handled a situation like this. But I would like to believe that I wouldn't have felt the need to diss my past relationship just because I am happier in my current relationship. However I do get your point completely @zoey123. Also, Meghana is a worrier and believes that her past is going to cast a long shadow on her current happiness, so maybe that's why wants to move away from it as quickly as possible. To her, embarking on a new trip means completely erasing memories of her previous journeys. Fair enough, I suppose. Different people, different ways!
