where to draw the line with a friend, I'm not sure what to put for subject

Tweet

Okay, so I have this female friend who is 27, she is a recovering drug addict and an alcoholic(trying to become a recovering one as well). For the past 2 weeks she and her husband have been staying with us, for reasons not related to this discussion. Tuesday afternoon she left here to go help her mother with some personal issues. When she left she said that she'd be back tomorrow, Wednesday. Well, Wednesday came and went with no call or sign of her. Then about 2 hours ago she called her husband, and more or less picked a fight. For whatever reason he ended up hanging up on her. She then called my cell phone and asked where he was. Her husband had asked me to tell her he wasn't here, so I told her he went for a walk. Now for the discussion part, in my heart I believed and still do that while she was gone she did not use any drugs and I wanted her to know that I had that much faith in her. I told her that much and that I believed she didn't want to lose my friendship, because I have told her I will NOT be here for her if she is on drugs. She replied that my love has conditions, that I do NOT know how to love unconditionally. Now this hurt me to the point that I pretty much hung up on her and was close to tears. I have 3 children who I love with all that I am and a parent's love for all intents and purposes is unconditional. Her words cut like a knife. The way I and my husband look at it is that my love has limits as to what I will allow with her, what I will do for her. I won't allow her to be in my life if she can not be sober for my personal reasons of which she knows. We, with the we being myself, my husband and her husband, believe that she is drunk because she is a very MEAN drunk and always says things of this nature when she is drunk. I am writing this discussion to help myself to not say something I may later regret and to get anyone else who may have been or is in my shoes views and advice. Thank you very much for listening and for any input!
