HI, welcome! I'm very sorry that you have to go through this and I think I understand what you mean about suddenly "waking up" to the reality. It can be very overwhelming. A wonderful woman in Naranon told me the first thing to do was breathe. It makes sense...we are so tense and overwhelmed that sometimes just sitting back for a minute and breathing deep helps us refocus.
There's lots of good advice here. I know that the Florida east coast is called the recovery capital of the world, so there may well be some free programs available. Maybe a list of some names and numbers might be a loving gift to your husband....the rest is up to him. I hope you will check for local Alanon meetings..They are so helpful for those who love addicts. Please keep reading and posting...I haven't seen anyone yet who hasn't felt better once they started taking steps to help themselves. Hugs
