good post latha... here's my POV
i think raghu is at fault in making promises without thinking through ... just like shivani he too gets manipulated by situation n goes on to make mistakes ... in fact sumitra n whaterever she does is partly or wholly his mistake ...but if u look at him as a good human being trying for everybody's well being , then he is not at fault ... but being silent about his sagaai n agreeing to marry shivani was a big fault too...he always had a choice to reject... bec nobody but him knew that it was his sagaai
similarly, i can't find any serious fault in shivani as all she does is being desperate in love ... she is just asking the man she loves to accept her love ... n the man in question isn't helping her by coming up with a simple 'no' , instead he is giving her excuses ... true raghu didn't bring up the rich poor diff , he said only about the mailk-servant relation... the rich=poor notion was planted in shivani's mind by bela... so the girl goes n tries to get rid of the reason for his excuses n once again asks him to accept her ... n here again what she sees is he is 'majboor' bec of sumitra ... till there i didn't find any fault ... but then again shivani insisted on trying to get raghu see her POV n accept her ... n that's where her fault lies ... but point to be noted is that she kept saying i am ur wife , how could u accept another woman... that's bec at that time she didn't know that raghu has already signed the divorce papers... but once she knew about that , she again persisted ... n that i find is her fault...
about latha... i have said it many posts ... she is acting on her dislike at shivani thus refusing to see from her POV... she saw sumi coming back n jumped on to the oppurtunity to get rid of shivani once n for all...
as for babs... there is no need to find fault with him... he is faulty from the beginning ...
