His drinking isn't just dangerous to him, but also to you. Before I left my ex was at the point where he was passing out with lit cigarettes and leaving the stove on all night. At the time I was desensitized to that behavior, but thinking back on it is really frightening. Like your husband, he has no desire to quit and doesn't believe he has a problem. Nothing I did or said could convince him of that. I had to start making boundaries to protect myself and my children because that was the only thing I had the power to do.
