As you wrote, as you won 498a (almost) why to take risk again.
she burnt her hand SORRY face already and she wounded poisonous snake, Do you still want to keep it with you.
If i am in your shoes, i will never dare to allow her shadow fall again on me.
She may try something else, if she come back again and she may stab herself and tell you stabbed her, this is from my own experience as my ex told so.
it is better to keep her where she is now. let her file any other cases, we are with you to fight against such misuse and abuse of Law.
