Will rohan marry nandini or not?

i think he will and later he will find out how much he loves kittu and he will start hating his mom and nanidini

It would be too late by then, cause Kituu might find someone else.
Remember "Hum Dil De choke Sanam" salman loves Ash but Ash don't go back to him later even she has the chance and goes back to Ajay. That famouse line Ash says "pyar karna tumne seka deya,lekan nebhana ajay ne"
Thats why the director shows Kituu gets humiliated alot by Sonia, Nandini at work & infront of Rohan, blamed by her family, her work effected & emotionally suffers alot cause of him. Rohan is nowhere to protect her. Yuvraj & Prabhakar are the only one who help her.
I think Kituu will dump him later, wouldn't take him back.

I agree with venesa but lets see now
