Detachment is really hard, but it is what you need to do. You are handling this admirably. It's so good that you can let go of him and love him at the same time.
He is undoubtedly still agonizing. I know I couldn't bring myself to actually say the word "divorce" until it was happening. Whenever I talked about the two of us parting, H would ask me if I loved him. I always got tripped up on that, because I did and still do love him. Leaving someone you love is like ripping your own heart out. I've been on both sides of leaving and being left, and it hurts both ways.
Anger is understandable, but it's also not healthy. You need to find a way to get past it. It seems like you are doing that. Keep up the tood work and take care of yourself.
