I just wanted to add my support and welcome you.
As the others said, nothing we do or don't do, nothing we say or don't say, can save them from their addiction, only they can do that when they are ready. If love could save an addict, not one of us would be here.
Take a good read around, especially the sticky posts at the top of this forum and you will find a lot of helpful information.
My son is my addicted loved one and it was meetings that helped me find my balance again and saved me from the unhealthy life I was living, chasing him around and playing Codie detective, trying to convince him of the insanity of addiction. I learned that you cannot reason with insanity and that if you hang out there too long, it will creep into your life too.
Hugs
