The way Robbie was getting Kasturi to dance indicated that she is just a puppet in the "great Robbie Sabharwal's hands". Look at the 2 women who love him Kasturi and Ishita - He uses them/treats them like dirt as and when he likes. When he misunderstood Kasturi, he immediately proposed/got engaged to Ishita. Now that his misunderstanding is cleared he wants Ishita out of his life and Kasturi back !!!. Their feelings don't matter. Its all about him !!
