Do you have separate bank accounts? If not go get one. If he is drinking he needs money to fund this. Don't let him take money away from you and your kids for his drinking. Flat out if you can I would take his wallet and his keys while he is passed out and make him sober up. But I am more confrontational than most. Isn't there someone with the Rehab place that can help when soemone relapses? I would suggest calling them to see what can be done as well. I really hope you can figure something out. You are a smart women. You are going back to school. Try to take a step back and look at any possiblity.
