THippy, just wanted to mention that the drinking you know about, the drinking you see, may or may not be all the drinking that actually goes on. You mentioned that you manage the money and that he gets a $30 allowance every 2 weeks. That would not have held my A for even one week, and yet I never knew that he was drinking at all.
You don't need to explain your household situation here, but I just want you to be aware that what you are seeing, moneywise and consumption-wise, may be only the tip of the iceberg.
This is why many here say to look beyond how much/often the A drinks when making decisions, b/c chances are so good that we don't know the half of it. All we DO know is how that person's actions affect us and our lives.
