Reason for RK's changed behaviour

I have a feeling there is more to RK's change in behaviour towards Madhu. It need not be revenge. May be RK realised he has cancer or some other grave disease when he got admitted in the hospital after Balraj's incident. He then wanted to maintain distance with Madhu and did not want to see her in pain when he dies as he is aware that she is madly in love with him. He wanted to become the same old bad RK so that Madhu and the rest of the family members start hating him .. I cannot believe that RK trying to save Madhu from Balraj by risking his life was acting. No one would know about his disease other than Bittu ji which probably will be revealed after many episodes . In the mean while shattered Madhu would want to challenge RK and get in to movies.

No offence but I really hope not!

Hmm...quiet possible ! I donno decease or what...but Revenge really can not be the actual reason . There must be a reasonable story behind it . If we look back we will see plenties of scenes where RK was alone , but was missing Madhu or hallucinating her...if it was all for revenge I must say those scenes r big bloopers & atleast from my side CVs wl recieve bloopers medal .
