Welcome, mtk! I'm sorry for what you're going through, but so glad you found us and posted. I did not have much experience with addicts before I married my XAH. What I have learned is that alcoholism is a progressive disease ("Either the drinking wasn't as bad when we first started dating or he hid it." Probably both). That I didn't cause it, I can't control someone else's drinking, and I can't cure it. Blaming others for their problems is very common - it enables them to justify continuing to drink.
I wouldn't say the general advice here is to leave your spouse/partner, but to do what is right for YOU. Al Anon can give you tools to help you start your OWN recovery, regardless of whether your husband continues to drink. I hope you'll find a meeting near you, or an online meeting.
In the meantime, read some of the stickies at the top. I started with this one:
