I don't think u need to involve her parents quite yet. She will def never want to speak to you again. Just let her know that u are there for her unconditionally, if she doesn't trust you to not be judgmental she will def not listen to you.
Thank you it is at a price now she will not talk to me at all I just do not know what to do I thought about texing her and telling her if she will not talk to me I'm going to her parents with it I'm at wits end I also thought about leave it alone and what ever happiness. Happiness. Whatever thank you very much
Maybe print out a local narcotics anonymous meeting schedule and leave it sittin around somewhere she frequents. Maybe If she had the slightest thought that she might have a problem, she might take it as a sign. But If she knows you left it, like jaharonov said, it could come with a price.
It is very difficult to give advice on how to deal with someone else's addiction. You know she is an addict, I know she is an addict, every person who write to me in this forum will recognize that fact. However until and unless this wonderful, intelligent woman that you love comes to the grips with this simple fact by herself, we can do absolutely nothing. It is sad, but true.
She probably sees addicts in her job, and denies that she is one of them. True addics will find every excuse in the book to explain, justify and excuse what they do. If you bring it up to her, you will get push back, it may even destroy your relationship.
If you feel strongly that she is hurting herself and jeopardizing her job, her family, etc., than you must take action. However it might come at a price. Read some of my blogs by clicking on my name (in blue) and then "blogs", see maybe she might be interested in reading some of them as well. Start a conversation going, if you are brave. Good luck to both of you...
