I understand why Avni made a plan B, though honestly that was wrong because now Mishti was proved to be Vidyut and Juhi's daughter so running with her away would be kidnapping! Neil was planning to hand the child to a child protection service, prove her parents are not fit to take care of her and then ask for her custody legally, that was a logical solution for the long run and it stays a logical solution for the long run even if Vidyut and Juhi run away with their child.
Now about making the plan B itself, you don't promise ur husband that you won't do something while he begged u not and to think about him at least once before doing it and then go behind his back and do it intentionally that too without the situation at that particular moment being urgent just because you think he won't understand, then don't promise at first place, because if you promise and u break it then don't blame him if he gets angry at you or thinks you don't value him! Sorry that's too much honestly, Me being a woman if my husband promises me something which we agreed on and he breaks it on purpose before even some situation comes into play then I would be deeply hurt, and if he does it every time I would honestly think about my value and reconsider the entire relationship, we know it's not the first time Avni did it, I mean the way Avni did even during Rang Mahal track when he said he would sign the divorce papers then sorry that person can't be blamed, if you ask me Neil is the most understanding husband I've ever seen on indian tv and he is too forgiving
We are not talking about intentions here, I know Avni's intentions are good, but think about it from a principle point of view!
Neil promised her happiness yes, more than once, but it's an abstract concept, he didn't break some practical promise when it was in his hand to keep it and that makes the difference!
