I don’t think I answered this directly with my post above, but I think the best way you can help him is by being your full, healthy self, for yourself. The danger of wanting to help an alcoholic (or any other type of addict) is losing yourself in the “helping”. Ultimately, someone who’s stuck in a hole has to choose to get out of the hole and take steps to make that happen (for example, joining a recovery program - for example, one of these: Online meeting resources). If they’re not taking steps to make that happen, you can’t force it. The risk then is that your desire to help can become more of a codependent cycle.
What you can do is be your full, healthy, sober self. Working that sober life and walking your path is a way to be present for every opportunity you have in life - and there are so many good ones to choose from.
It’s a hard path, I know. Keep reaching out here. You are not alone and we’re all here with you
