Welcome to the Forum!!
You'll find Al Anon very helpful for support, advice on how to deal with things also can be found, but be careful on thinking you'll be able to seek advice on how to change/fix/cure your husband, you won't find that.
The reason being only HE can change himself, but he has to WANT to, the main focus is for you and your family to receive the support you need to deal with the situation!!
