In my experience with my XAH he lost the ability to feel remorse or shame for all the stuff he did. But- he really could still blame me for little stuff. They just lose the ability because their brain is getting eaten up with substances. And I read here too some of them are jerks and then you add a substance and it gets worse. It gets better and better the less contact you have with them. They try to hook you back. But down the road you will be so much better off. Too bad you had to give up the dog. I had to give up a cat. THAT hurt.....
