HI R and B,
I'm sorry for your anger and frustration.
Yes, I deal with this every few days.
I have worked very hard to put "myself" away...that is, to shove deep down inside the anger and rage I feel at that man, who makes "rules" and continues to not do them, in re. to DD and their visits.
He interprets everything rather than "JUST DO IT!!!", I wish to scream this at him, like Nike tells us.
I cannot be in the same room as him either, for the reasons you describe and others.
The anger...oh, the anger feels like fire inside and I feel my face heat up (not from rosasia for once!). I feel suddenly like I am physically strong when it comes, but I go and exercise or something instead. I put the electronics down so I won't communicate, for it never, ever helps.
We are in D process and I feel the anger when correspondence comes from 'them', because Perv or his incompetent L is putting things as my fault that are Perv's responsibilities! So this only fuels my anger.
When I have a beef-grievance-about or two him, I do not contact him in any way, shape or form. I have a friend and a cousin I lean for that and I also journal the stuff that causes it and show L instead. It really helps when I calm down to do this, for several reasons.
-I've kept NC.
-I've not shown that man any emotions.
-I've made a list that judge may see eventually and that matters more than me being able to yell at him. He won't care if I do that and it may even be an ego boost, if he knows he upset me again.
I won't get an apology either, I don't expect any. I expect him to go away, for what I get is silence when a problem is past.
Also, if you can take deep breaths and count or something prior to replying, it really does help. I never, ever reply right away anymore, because my emotions spark so high. Sometimes just seeing his real name on my phone sparks it now.
I'm sorry to be so long and yes, I am in the same place.
I wish you some brief minutes of the peace that you seek and then for them to grow.
