My husband’s 35 year old son is a heroine addict. Says he has been clean for 5 years, but many problems have developed from this addiction such as he has been unemployed for the past 7 years, and has been asking and getting money from his father. His father is an enabler and cannot say no to him no matter what he asks. How do I stay in this relationship and not go insane? We have been married for 14 years.
