It's either the family admits they have no control or they can blame someone..that being you. He will need to work on his relationship with his family before they will see you differently. Who knows what he is telling them. You should focus on yourself and your family. And your husband needs to focus on his recovery. It is his no one else's. There is nothing anyone can do to make him use and nothing anyone can do to make him recover. It's in his control.
