Debysu, I just spent two weeks teaching in a prison and met a whole lot of addicts who were working their recovery. It is not the worst place, nor is it the end, as Vale put it. It sounds like you are putting your LIFE and your husband's at risk by continuing to do what you are doing with no change on his part. Get a restraining order, call the police, do whatever it takes to keep yourselves safe. His addiction is running the show and there's nothing you can do besides protect yourselves from the fallout and destruction. He is a grown man.
I am the mother of a recovering heroin addict, so I understand and feel your pain; I wish you peace and courage.
Remember the Serenity Prayer and take it into your mind completely: God, grant me the Serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference." This helps me every single day. Blessings on you and your whole family.
