I agree with Pari
Even if Onir is found to have a past ...any past , Purvi has no grounds to lay any guilt trips on him as it should make no difference . He accepted her with a sizzling past with NO QUESTIONS and that was very convenient and fine for her . He did NOT employ a private detective to dig in her past and its secrets . She should do same ...NOT mind his past .
She made a marraige with him based on LIES . She let out bits and pieces of her life in instalments when they were unavoidable and convenient .
She had NOT told him about her foster family
She had not told him how she had forced her lover to marry her sister AFTER having sex
She had not told him that she was carrying jeeju's child
She had told him NOTHING .
And he had questioned NOTHING , refused to judge her and merely offered her comfort by being there for her ...so much so that he LOST his medical license for her .
Arjun should be slapped silly for hiring a detective to find out about Onir coz Onir never hired one to find about Purvi .
