If the W wants starts a R talk but I feel I am not ready or caught off guard what is the best course of action?

It felt like I was caught a bit this morning in the text exchange referenced in my previous post. I think I handled it ok but could maybe have done better.

Our pattern has been about every 7 to 8 weeks we have a M/D discussion initiated by my W. We are there now so I just have a feeling after this morning and the stress of not having much money will bring out her frustrations and they will be directed at me, of course.
