Yes Kokila's love is conditional, it's like hat with Kinjal, they still have not reconciled, with Gopi, Gopi has to keep proving that she is better then others like Rashi, with Aham too, if he doesn't do what she wants too.
Gopi should leave, she can't make them happy, she doesn't have the know how/intelligence to keep Rashi at bay to be what Kokila and Aham want.
