My daughter will be 18 this summer and plans on moving in with her boyfriend who is 21 and lives in his parents basement. As far as I'm concerned, she is on her own and can drink if she wants.
So you've washed your hand of your daughter's drinking cos she's technically an adult ( your quote) but you still continue to enable your husband and allow him to have free rein in your home as an active alcoholic under the guise of being "sick" with all the mayhem and upset that entails on a daily basis. What exactly do you think will happen to your younger kids once they are your daughter's age ( or younger) if this situation continues? It is not a coincidence your daughter has issues with alcohol.
