My husband needs alcohol rehab but refuses to admit he has a problem?

You got a very big problem here. I am the son of alcoholics. Both of my parents were alcoholics, and they both denied that they were. I have lived through what you are living through now. There are places that will let you admit some one without payment. However you cannot force some one to go with out their consent, even if it means harm to them or some one else. What i suggest you do is to do an online search in your state, and or city, for clinics or specialized facilities that you can talk with first to get them involved in treating him. 99% of them will do an intervention with you and your family, and then take him for treatment. Some of them will not charge you, but you will have to find that out your self. Good luck and may God look after you and your family.
