There's no single answer here. Some former addicts manage fine, others don't. My wife and I have some agreed boundaries here - no alcohol in the house ever, don't drink around me, and don't come home drunk. If she has a glass of wine with friends at a lunch (which she does, rarely), I don't care. I would not live with a regular heavy drinker or with alcohol in the house, since given how far down the hole I went years ago I wouldn't put up with the risk, but that's me.
