Women complain about problems because they want their problems to be acknowledged, while men complain about problems because they are asking for solutions
This is what happening between Krishna and Pratigya. Krishna really thinks that Pratigya is in love with him and she is just hiding it and not able to express it. So he wants a solution to all this "kit pit". And he wants to get over with all the problems Pratigya has. Pratigya thinks he is only obsessive about having her and for this sake he destroyed her family. She wants Krishna to accept he had made their life hell (which by the way, Krishna is completely unaware of).
In fact, both are right at their position. Their opinion on other is determining the behavior towards the one another. If Krishna acting weired lately that is because a frustration is brewing up within him. If Pratigya is unable to see Krishna's inner values that is because she is prejudiced.
Frankly, I feel their contention is also a form of their romance and cute to watch it. I would rather watch Krishna showering Pratigya with his love and She gradually responding to it. There is no right or wrong about most of the problems between the couples. It's just that both of them have to mend little bit and move on in their life. The love in their relationship matters more than any idealogical principles of life. Idealogical principles are subjective.
