Thank you edenchai for your response.
We are broken up as of right now, I kind of don't want to lose her, but from reading what you said and being in her life is a way to inadvertently support her habit sounds very true.
I just finished talking to her and she wants me to understand she knows using every day is bad but occasionally isn't bad according to her. I told her I don't agree with her but I won't change her, and I think just by me doing that and sticking around it will negatively enable her using... I don't want to walk away but I guess I need to..
I hate trying to rationalize not using at all, occasional or not.
