Very, very well done, Mila, on how you handled the convo and yourself.
For the record, I don't think it's not DBing to have the occasional R discussion (when your S is in the right frame of mind). The DBing part comes in with how you comport yourself, showing a new calm, strength of mind, confidence and control over your emotions. Tomorrow he may not remember the conversation, or may have rewritten it ... but in the long run, he will probably be impressed by the new you.
