Any response that is an emotional reaction is keeping the ball in play in the game. If you truly want the game over, don't play.
I use the example of unplugging a video game. People can keep pushing buttons but nothing happens.
What he does is no longer your concern. You get to be angry he left. You get to be angry you were betrayed. You get to be angry that you didn't get the marriage you wanted in life. Don't hurt yourself further by showing that to someone that doesn't care and will use that to hurt you further.
Don't worry. I ended up taking a nap with the kids and never responded. Im still super pissed though, because I am all of the things you mentioned and more. But I won't reply.
