HURT: my ex didn't show remorse either and he blamed. It was more hurtful than the actual cheating.
As the weeks went on, I saw he was a little more hurt by his actions, but I think you're right, if they show emotions, they will probably break down and drink.
It's a good idea to both take time away and let him work on his issues and sobriety and you work on yours.
When my ex and I first separated, we also decided to move on and work on our own selves, but with no expections of the outcome.
I've not seen him and we don't speak so we are just living our lives now.
