Rhode, glad you're here. How old are your kids?
Perhaps you could arrange for daycare or after school care till you could get them after work. Then, at least her drinking wouldn't physically endanger them.
Once they're safe, you could relax a little and figure out your next move.
Please stick around, lots of wisdom and understanding here.
Other things I did was read "Codependent No More", it was suggested to me by the DA as he escorted me to the witness stand in our CPS hearing. I also attended Alanon meetings, as court ordered by a fierce CPS judge.
My wife couldn't quit, and we divorced and I was granted sole custody of our 5yo daughter. She's 9 now, and she's been affected. She's also smart, out going, does good in school, and by all out ward appearances, seems to be unscathed. But she's been affected.
Thanks and God bless us all,
Coyote
