Hey Fedup,
Welcome to the forums. It sounds like you are in a very turbulent place at the moment. You have decided to seek advice, experience and support about it so that is absolutely fantastic. As has been said check out the family and friends forum, there's going to be a lot of information in there that will be beneficial to you and your situation.
As a recovering addict I can just say that your husband will not stop drinking until he wants too. No amount of cajouling or pressure will change him but hopefully he will get to a point where he wants to change for himself.
Are there any free relationship counselling services in your area. It may be worth checking to see what other type of support is available for you in your local area. I wish you all the best.
Natom.
