I get the anger, I've been there and done that, and I am happy to say that it does start to dissipate. I will also say that I don't look back at anything I said or did in anger as a positive, and while I won't say that I regret it, I will say that I am happy that I limited those reactions to my anger strictly to my ww.
There were times when I hated that my WW did everything that she did and walked away with my son, dogs, furniture, basically our entire life minus me and the house. The thought of hurting her through my son crossed my mind a time or two, but I was always able to put what I believed to be his best interest above my wants, and I'm glad I was able to do that.
Although there was a time when the thought of him hating her for tearing our family apart appealed to me, but when their relationship actually became strained and distant (without any input from me), it hurt me to see him distant with his mother (I'm very close with my mother). In my opinion, my son deserves to have a great loving R with his parents, independent of how they feel about each other.
I wouldn't tell a father that he's wrong for telling his children information about what's going on their life, but I would hope that it was done in a loving, caring way, that wasn't done in a way to sway their R with either parent.
Your angry, and you probably will continue to be angry while you are forced to deal with her regarding the D, I hope that you can find a way to deal with that anger in a way that you won't regret later, when you have leveled out.
for what it's worth, I stopped talking to my W, I only communicated via text (or email when needed), and it allowed me to keep my cool and delay responses or reactions until I calmed down. My son was 16 when I started doing that, so I communicated directly with him regarding schedules, etc, and limited communication with her to only things that we HAD to discuss.
I hope you find a way to lose the anger, it doesn't have any positive or beneficial effect on the situation. It took me a long time to realize that she doesn't hold the control over me or our R; she didn't discard me like I don't matter. She did something that I won't accept in my M and I am moving forward on my own.
