Hi...welcome to SR. What would be the best thing for you to do now is find alanon meetings and attend as many of them as possible. Get the free literature and learn all you can about the disease. There are lots of books out there about alcoholism. Check out Melody Beatty. "Getting them sober" and "Co-Dependent No More".
Grab a coffee, put your feet up and dive in. You'll find that what you're going through is typical. But the most important thing is for you to worry about you and taking care of your mental, physical and spiritual wellbeing.
Blessings
