But Aditya has not dumped Malini, he just told her that he was forced to marry Imlie and has fallen for her. But he has never explicitly said he wants to leave Malini, he kind of left it hanging for Malini to take care of it, which she did by filing a divorce. She put effort in moving away, but she is in an emotional turmoil and eventually she will move on but she needs to do so at her pace.
Aditya explicitly told her that He wants to be with Imlie and he has hurried out to find out Imlie's whereabouts after truth revelation .Malini proposed divorce and he accepted then they both filed for it . Is not filing divorce means an end to a marriage but it is Malini who comes back again and again - desperation!!
