You did the right thing, hopefully it will help him in the long run. I think you have been very brave and very wise,why let the alcohol ruin 2 lives? You have done all you can, it’s up to him now, the help is out there for him when he’s ready. It won’t be easy, he won’t like it or enjoy the process but he does have a choice. You have made it very clear to him with your decision and refused to enable his addiction any more. I hope you find some peace and happiness. I am nearing the same decision myself with my 32 year old son, not quite there yet but for his future and my sanity it may have to happen. Take care
