Welcome to Soberrecovery Joy! I hope you find lots of support here.
The best thing you can do in your situation is take care of yourself and find some support. If you haven't done it already, try a couple of Alanon meetings. They are all a bit different so try a few. They don't work for everyone but for many they are a life saver.
Also look for Codependent No More . It is a bit of a bible in these parts and can be helpful.
As you, no doubt, have noticed, loving an alcoholic is no joke. What you are dealing with is super painful. Unfortunately you can do little to nothing to help him as he walks this journey. However you can improve the situation by getting help for yourself.
Keep reading and posting. Let us know how you are doing.
