Prachi has become irresponsible for the following reasons;-
First the whole thing abt nt disclosing.. unnecessarily adding troubles to their lives!
Now suicide i didnt expect this from her i thought she was very principled n wt abt her family? if she cares so much for her family wt wud they fel if they hear tht she is dead or smthing (nt tht she wud be bt still) n wt abt ritwik..? i dun think every1 knows its suks kid so who will tak care of him? milind cud bt we all knw he isnt n expert n he hasnt got the time so shudnt prachi be more responsible abt her actions.. otherwise i dun see hw prachi is supposedly more mature thn the other characters?
She is equally on fault!.. n if milind insulted her.. she insulted herself by admitting to having an illegitimate kid.. wtever the circumstances.. she cud have handled it better!
Would be glad to hear ur take on it.
