Wife files divorce after I confronted her 2nd EA

[CWOL]

WW asked me about payments for her separation agreement. I told her my L advised that we needed for her L to file the stipulation to remove her RFO from the calendar first, before I make the payments. She said, "Fine, I will check with my L!" She said it in such a way that was really infuriating to me, with a total sense of entitlement and lack of guilt for what she is putting us through. I find that whenever she brings up the D or M issues, I get very angry. Thus, I have kept all these discussions to the very minimal.
I've signed up for some DB coaching. Hopefully they'll give me useful tips on how to handle this situation and also to control my emotions.
