She likes the liquor more then she likes you.

Having a problem with drugs or alcohol is a pretty big deal. Suddenly, priorities are shifted around and the demon becomes all-encompassing. What she does to you suddenly takes a back seat to feeding an addiction. If you suddenly discover her problem, 9 times out of 10, it’s a deal breaker. The exception is if you helped to contribute to that problem, or she developed it in some way because of you. In that case you’ve got an obligation to the issue you’ve helped create. It’s a treacherous tightrope to walk, best of luck.
