Can I clean my husband up by myself?

I am a addict that got clean 2 and a half years ago. Powder was my drug of choice and it was hard to stay clean but I did. I am now faced with a very real and frightening problem, My husband. He is such a wonderful man. When we met we both had problems with drugs but through mutual trust and respect we got clean. After moving to his home town 2years ago we stayed clean and vowed to do everything in our power to keep clean. About 5 months ago we were planning our wedding and my husband came to me and said that He would like to get some crack. I was so angry that I told him to do what he wanted. That was my mistake and I regret it everyday. He went and scored some rock and came home and smoked it, and we did not talk for two days. I told him that I was sorry for not stopping him, but I did not realize how much I would grow to regret that fight. We are now two months married and I find out that he has not only continued to use but he is doing so on a daily basis. Our bills were not getting paid and I have now taken control of the finances. My question is How do I do this? How do I get him clean? He is so responsible and works everyday but after work he just wants to be with his pipe and lighter. Does any one have any advice for me? And before everyone says professional help, that is out of the question because he will not go. He can stop he says but so far nothing has worked. I do not want to leave him because I love him, but that is where I am afraid this is headed :'(
