Jeff...
Don't give her a choice...this is your sanity and serenity we are speaking of..
I would tell her that he only option is Choice A.. this gives you a chance to have some space from all this and a chance to work your program without your addict in your environment..
You know if you give her the choice B she will have an excuse not to help around the house or get a part time job... Oh she will promise all these things while you are giving her the options but following through is a whole different matter.. Addicts tend to tell you whatever you want to hear..
Before you make any decisions.. Base your choices on you, your recovery and your sanity...
