He misses work because of drinking. He urinates in random places. He gets argumentative. He's been in fights. You have to cover for him because he passes out in the house. He tried to drive while drunk. He was robbed. He's 'acting single' with his buddies and commenting about how fit the girls were.
The challenge is, HE doesn't see it as a problem. YOU have a problem with it. As someone whose dad was a functional alcoholic, I can say that Mom putting up with this allowed me to view my boyfriend/fiance/husband's drinking as normal. Is that what you want for your children?
