As holding said, she's goading you right now - definitely not the mature way to have this conversation. And as Joseph said, this is the type of response to give when you asked to simply put in practice what she asked for in the first place - a separation. She knows fully well that you don't want this. You've already told her in many ways.
Don't say anything about the emotions being too high. Again, don't do anything tonight. Come back tomorrow and see what else has been posted about this by others.
Yes, you can say a few different things, but that can wait until tomorrow. See what happens from her end, and others have to say.
Sorry, small edit:
And as Joseph said, IS this the type of response she can give to you when you asked to simply put in practice what she asked for in the first place - a separation.
She took your boundary and kicked it up a whole buncha notches. Trust me, your assertiveness got to her.
