To answer the question about whether a DUI means someone's an alcoholic: it means someone is either an alcoholic or really really dumb. I know it used to be the case that people drove drunk all the time, but really, my generation and younger know all about it. Whenever I go out the person driving is the one who doesn't drink--doesn't everyone do it that way?
My AH drove drunk once. I didn't find out about it till afterwards, but I told him I'd call the police on him if it happened again. I also took away the car keys whenever he binged from there on out. He got whiny about it: "I'm not going to do it again! I stay away from the car when I'm drunk!" but I told him I wasn't about to have some dead kid on my conscience-or get sued.
