Hi Dominica, welcome. I've been reading your posts and I am sorry to hear your rehab option is not available anymore. I would strongly suggest you don't give up hope, as a solution may be just around the corner, but only if you make a concerted effort to quit drinking.
It is probably a good idea to go and seek medical advice as cutting back from your current levels of consumption could be life threatening. Continuing to drink at these levels or higher should not be an option to you right now. Do something. Anything you can, something that is a step in the right direction. Even if that's a medically supervised tapering down, it's still a step forwards.
I am not going to give advice concerning your husband because I do not know the whole story. Relationship decisions should be made with a clear sober mind anyway. Good luck and please keep posting here.
