I picture addiction as a weight, like an anchor that my son has wrapped himself in. Hanging on will only drag me down with him. Letting go frees him up to find his own way to detangle.
Only you can decide what is right for you. If love could save our addicted loved ones, not one of us would be here. That said, I stuck with my son for years and years until "his" addiction almost killed "me".
I am glad you joined us and hope you find the support here you seek. Take a good read around and learn a little about the stories of those here who have walked where you walk today.
Hugs
