Personally...I would get as far away as I could.If you feel capable of being clean when she isn't around then...for your own quality of life and health you need to censor the influences around you.On the other hand,there's a saying..."No matter where you go...there you are..." In other words...it isn't the influences and opportunities surrounding you which ultimately choose behaviors...it is we who choose.And if an addict does not want help there isn't anything or anyone who can help.They need to come to a point where they choose it on their own.You could look for some numbers to hand to her,explain that your own wellness has to come first....and then pursue your sobriety.
