Problem is Roshan are emotionally attached to each other ..Aman way of showing he is hurt by hurting Roshni by saying mean words to Roshni ..but did he actually mean it?? No na ..he is impulsive end up in saying worst ..He is unable to control his words when it comes to Roshni ..But with his family he wont do that because his relationship with wife and family is different so reactions also different ! He loves his family protective they are his world but Roshni is his life and she is his heart..but he is not treating her well may be don't know how to treat her from the start..Now From his side thinking treating Roshni this way because she hurted him but once he knows truth we know what happens ...He should compare Roshni with his family and hope he realise how wrong he is ..and he should accept Rosh as his family as she deserves respect and love like his family members ..She is not here just for sacrifice her life for them..Hope redemption track we get good mature conversation between Roshan!
Nowadays he is hurting Roshni by saying mean words but he actually hurting himself as he loves Roshni ! He confessed this na sending Roshni out of his life is big punishment for him! He actually wants to show he is leading miserable life without her but ends up hurting her with mean words!
