However I don't see it as a flaw, Mauli has way to much care to give. As for initiating Kunals dream then I see only her love. His dream is now her dream, doesn't that come normal in married couples, well at least I'd hope so.
The removal of the implant, then I agree it is a joint decision however it is her body and she now feels ready to be a mother and hence by undergoing surgery (though that ain't no surgery lol) she's telling her husband she's ready for the next step, of course seeing her character so far I'd assume she'll tell him and plan a family accordingly as they mentioned in a previous episode
So in hindsight though frustrating but I don't see a flaw in her, her only flaw is that she loves him too much and to be frank he isn't worth that love
