GF what I am saying is the way I think he feels. It has nothing to do with you. He is depressed and in a fog. Anotonia bascially has it right in what I was saying.
No I don't think the emotional ties will be cut but he may feel that way. He just wants his pain to end. He mistakenly thinks that you are the cause of it. So when he gets rid of you he thinks his depression will end and his pain will go away. That right now is giving him a lift.
He will find out that his pain will NOT go away even after he has divorced you.
At that point maybe he won't blame you anymore. But I am mindreading here.
