I don't see how it can get better unless he gets sober and actively participates in a recovery program. It WILL get worse if he doesn't, as you already know it is a progressive disease. It doesn't just 'go away' all by itself one day. There's certainly hope for a life together but it all depends on what kind of life you want it to be. I know of quite a few happy healthy success stories -none of whom though are still in active addiction. I would continue to go to the alanon meetings. Even if they are older they do have the experience and this is where you will get the tips for dealing with this. Maybe try another meeting in a different local if this one doesn't seem to fit you.
