despite my earlier post,i understand why riddhima decided to sleep with sid.she just realized she still loves armaan.shes married to someone but loves somebody else.her sense of duty is being undermined,so she decides to end it by quarreling and sleeping.i know situtions like this,it happened to my best friend-only she had a boyfriend and the guy she liked was her best friend.she quarreled so badly with her bff.i also understand why she married sid.the only thing i REALLY blame her for is braking sids stuff.
