You are not alone. One of the scariest things that I ever did, and one of the best, was walking into my first alanon meeting. It was there that I learned that I wasn't crazy. It was there that I learned that I was not the only person in the world dealing with this problem. It was there that I learned that, although my spouse's behavior was bad (so was mine) it was also common to this disease, predictable, and treatable.
Your husband may get worse for a time as you get better. Keep getting better anyway. He may accuse you of all manner of untrue things. Keep going to alanon anyway. Alcoholics are very manipulative and dishonest people. Don't let him bully you into stopping your own program. If you get better, the whole family may get better. Mine did. Be careful though, I said "may get better". This is not guaranteed. Your program is for you not for him. Get better in spite of what the rest of your family does.
Good luck and welcome!
