You did the right thing. It sounds like his little tantrum is messing with the fantasy of getting divorced and still having you as a friend and probably a "piece" on the side.
Let emotions calm down. You don't need to think about him right now. Concentrate on the kids. You need to be the mature one and keep the family intact. Detachment is so that you can stabilise your own life and then if he comes out of his fog he'll see that you were there all along.
Just because he makes you sick today doesn't mean it can't be fixed. You just need to not think about him for awhile. Focus on the kids and make their time special during this turbulence. You're doing fine, better than some and I applaud you taking the step to get outside help when you saw things going pearshaped.
Now, what are your goals and what are your plans for the week. Let's not hear anything about the H and his skank for awhile. What are you going to do for you the next few weeks?
