Separation. It is a completely cliched track but she needs to be
far away from Kunj. That's the only way that she's going to realize his importance in her life. He has helped her out in all the little ways and big catastrophes while she merely took advantage of him.
She needs to recognize that her behavior towards him has been completely wrong and that she needs to mend her ways. She needs to start comprehending the situation around her rather than jumping to conclusions and then sticking with it.
In short, she first needs to grow as a person before she can even think about falling in love with Kunj.
Plus, Kunj needs a major break from Miss Syapa and the living hell that his life has become.
