i agree she is not responsible for the past ... but she is responsible for the present , she is giving chance to marriage by forcing her on this relation ship which doesn't have any values according to her husband..
plz dnt say that she is following her kamala ma(because she didnt obey about the kamla for her parents but y she is obeying this?)
before marriage she dnt know about ragna but after marriage she knew everything and how much ragna loves each other( i think on party night while raghav asking hand of kalpi from kamala he said how much her dauhter changed his life by bringing happiness, love care etc... because of hamala and pakhi dumbness they didnt realise but now she can realise right). i hope she may take right decision not being in dilemma...
just it is my pov... im sorry if i hurt anyones feelings.
