There is not a darn thing you can do to change him or get him to think rationally right now, so just make sure to look after yourself and your children. If money is a problem, don't give him any, not to control his drinking but to control your own financial responsibilities. If he works and spends his money on drinking, there isn't much you can do, but learning to look after yourself and your own recovery will take you a lot further than worrying about his.
It's just a losing battle, and one you don't have to fight.
