You have expressed Sandhya's feelings well. Added to that, until the point she achieves her goal/dream of becoming IPS officer, she cannot commit herself to marriage, love, family, etc.
^^
for that she must atleast confess to sooraj what were her dreams and tell frankly she will not commit until she achieves it & request sooraj to marry other girl and move on..still if sooraj wants only sandhya he can wait for her or even help her in her studies... but she has completely broken his heart 😔 that too when he was looking at shadow as if he is lusting her ... i totally dnt understand what are sandhya's plans ..
i agree sandhya might have tried hard to love sooraj but she couldnt and after seeing kirthi she is completely frustrated that she could never reach that benchmark ... but she has to look from sooraj's pov also 😔 ...she should not have shattered the man who supported her 😔 ...no need to love but respect his feelings...
