Lucky you are doing awesome and you have a right to get frustrated. I think the best thing you said is H's parents need to stop enabling him. I feel the same with my in-laws as well. H has a problem and they should at least be asking where his money is before he gets more. My H is the same way except it won't ask his parents for money, although they would give it to him in a heartbeat. It is very frustrating, but you are right he is still taking positive steps forward and you can't expect him to change overnight everything he has done for many years. Be thankful he is going to the counselor and taking his supplements. Take the time to vent so you don't go off on H, maybe take some break from H, but at least he is calling you (it seems kind of regular).
You just keep doing what you are doing because it is working, and don't forget in all of your taking care of H and S...take care of YOURSELF so you don't get drained. Maybe look into a support group for alcoholic's families so you can make sure you have someone to help you with that aspect.
