What's manipulation exactly?
Playing a loved one, or one's family with words to keep the person(s) enabling the active A so said A can continue to get and use their drug of choice (DOC).
Being they words of blame (causing guilt) or words of wheedling and begging, or being super nice, or threatening to leave and it will be all your fault, or threatening suicide and it will be all your fault, etc
