Welcome!! You have found a great place for support.
Remember you didn't cause this, you can't control it, and you can't cure it.
An alcoholic will drink if they want to . they will find any means. My Ah drank mouthwash.
But enough about them, Some things that helped me in the beginning were reading/educating myself about the disease. I found the books "Marriage on the Rocks" and "Getting Them Sober" very informative. They are quick easy reads, I highly recommend them.
I also starting going to Al-anon. I was able to talk to people "in confidence" about what I was going through. It feels really good!
Also posting here helps. There is a lot of knowledge on this board and many have been through the same thing you are going through.
:ghug keep posting and reading!
