Honestly fightin all WW's behave alike but they don't all feel the same. Your W could be 'sure' one moment and then not the next, it doesn't matter because she's not going to tell you, and if she does you most likely will not believe her. WW's act a lot on their feelings of the "moment". Your W will move it as fast or as slow as she wants I don't think stalling it will be beneficial, but IDK I'm not in that situation just yet.
MY advice is don't reply right away. to this or anything, think about it, sit on it, discuss with your support system and THEN get back. This is about you too. don't forget that!!!!! Even if it takes 24-48hrs to reply, it's OKAY! Never reply when you're emotional, pretty sure we've all done this (I have) but it seriously does NO good.
hang in there and hang on, this will be a bumpy ride. we are here for you
