Your husband sounds really supportive. Don't concern yourself about what he's doing though or if he might have a drink, If he doesn't have a problem it doesn't matter and if he does have a problem then there;s nothing you can do about it.
The fact is that whilst he is not drinking to support you, you are still drinking.Your energies will be better spent looking for more/different support in how YOU are going to stop drinking. Praying alone isn't doing it, perhaps look at more F2F support or anything. Every day you post yet every day you drink so what you are doing isn't working. If you really want to stop more than anything then concentrate your energies on what you're going to do differently so you don't drink.
Be honest with yourself- if you are not prepared to do anything else to stop drinking then how are you going to stop? As they say nothing changes if nothing changes-it's so very very true. If you really want to stop you will do whatever it takes. It takes action and commitment and you have to really want it,
