Also mostly cuz these two are not ready, Avni and Neil have so much to discuss and sort out in their life so bringing in a kid at this point of time would just complicate things for them. Plus as a Avneil fan, I want time for them to romance properly, till now they're not upto that realization even that they love each other. I want Avni to cherish her happy family moments, she shouldn't feel obligated to adopt because of Neil or in order to repay what Neela did for her.
