As a employer, please give her another 10 mins. to clear understanding what does she want. Perhaps she wanna to say something, but last time was too hurry that she hold the words.
Better to hear from her and plan for the next step.
Do not spend money and time to change a new maid before clear out.
Ask her if she willl resign by her own or you give her one month notice. If she didn't want to do any longer, better let her go. And you may start to look for another maid.
