There is nothing that will stop an A from obtaining their alcohol. The hard part for us is to detach from their behaviors and let them do what they will do. That means we don't pour out booze, don't hide keys, don't let air out of tires, etc. All those behaviors do is keep us in the spin cycle, it doesn't stop the A. We have to learn to get out of their way and let them choose their path. In the meantime, we choose ours. I don't know if you attend AlAnon, but that's a great place for you to sort this out.
