Like yourself, I've heard similar sentiments from my W since late-Jan this year but in differing tones; sometimes it's heated spew, at other times it's delivered cold & Machiavellian.
Not experienced enough to offer good advice at this stage, especially as I'm living in a difficult enough situation myself, but sounds to me like you handled it well considering the circumstances; certainly better than I would have.

Rather than passion, think it's more likely an aggressive reaction she's after to further fuel her delusional thinking/behaviour.
Stay strong; hoping calmer times are ahead for you.
