Well, that is your decision to make, but if you do decide to get out, be ready for his quacking. That is his promises to cut back or even quit drinking. His assurances that you mean more to him than alcohol. His willingness to do whatever you ask of him if you'll just stand by him. Even if those quackings don't come right away, chances are better than good they will come after you leave the relationship. Just be ready for them and don't fall for it. Good luck!
