I was just about to suggest the same thing, LTD, but you beat me to the punch.
When my boyfriend was actively drinking every contact from him--whether via phone, e-mail, letter, or in person--was an attempt to hook me, an invitation to rescue him, an opportunity for him to tell me how miserable his life was (and how I was responsible for that), and a manipulation tactic. Eventually I learned there was only one way to protect my sanity and that was to have absolutely no contact with him.
I learned that when it comes to the games that alcoholics play, the ball is in my court. My boyfriend could try and lob all the manipulations at me he wanted to, but once I stepped off the court the game was over.
It seems to me you have two choices here: return her serve and keep the game going, or declare "game over."
