I say this as the mother of an active meth addicted daughter.
And the wife (25 yrs) of a man, who....at 55 years old...has decided to become a Vicodin addict......
When you admitted your use....she was probably relieved to have an answer as to why things were the way they were. I know I was.
Because of her history with her family.....she simply doesn't have anything to offer you.
And it's not reasonable for you to expect it.
This is why we date....to see what the other one brings to the relationship.
You have brought addiction. She's not interested.
Be kind.....let her go....and go deal with your issues.
