Seems like its tough around your house right now.
If your children and you are sacrificing your sleep for his drinking and partying, that is not what al-anon has in mind in regards to not confronting him..
He chooses to drink all night. OK, his choice, he is an adult and has that right.
You can choose to leave the house, or
then unplug the phone, if he is pounding on the door you could call the police.
Ive done this myself.
Who is making the choices for the children in all the commotion with him and his drinking buddies?
