Sounds like she did all that she could...all the way up to being the last in the family feeding him, etc. She is not alone in cutting contact, just the last one to. If her analogy were true then everyone in the family is at fault. But sadly, he knew what needed to happen. It is so heartbreaking to hear this. So many addicted ones die alone. My dad did. It's not something you ever want to happen to someone you love. I would tell her to try and remember the good times, focus on those good moments and in time the pain will begin to go away. It just takes a very long time.
