How wonderful (and awful) that you got to see the inside of his emotional brain! These are the things that he is really feeling inside, despite the fact that it was alcohol induced.
He is finally starting to realize what he is doing and what trouble he has caused. However, without the alcohol he may not feel so brave and may start to retreat because he was very vulnerable with you. Plus if he was drunk he might not remember some of it.
I think you handled it AWESOME 3. I love how you said you didn't hate him just you hated the decisions he has made.
I think this is where you need to let it lie with him and not bring it up again unless he does. He has admitted some serious things and he needs to stew on that and sort it out in his own head. I still think it was amazing to see inside the mind of an mlc'er!!
You're doing extremely well if you ask me, keep doing what you're doing.
My two cents.
