Hon which is of utmost importance, you and your children or him?
Want to help him? Do absolutley NOTHING for him, if he falls down leave him there, if he gets busted do NOTHING!!!!! Alkie or addict, the longer folks help, the longer it takes us to hit bottom hard enough for us to begin recovery.
Take care of yourself and your kids, you can NOT help him, he needs to help himself.
Go to the friends and family forum here and go to alanon if you can.
Please for the sake of your children, do NOT go down the toilet with him.
