Ranbir doesn't catch a break. Kanya is such a cow. When Ranbir was saying he was ill Kanya instead of going to Ranbir she she went and stood right next to Chunnu and then when Ranbir was in bed with the whole family Kanya admitted she wanted to go with Chunnu instead of tending to her sick husband. Means Kanya is heartless the only person she cares about is herself.
Ranbir stop feeling the love and fall for Archita that should do the trick is not he's better off without her.
