Thats a tough one dude. If your doing all this just for the poonie than get rid of her. Bt if you do love this girl and want to be there for her (it will be tough, long journey) than stick it out. 95% of people with addictions have a relapse at sometime ( my own number, I don't know the stat). I would just play it out for now, if she hits the pipe more than it may be a lost cause at this time in her life. She will choose when to quit.
