Welcome to SR!
I am a recovering addict, as well as a recovering codie (codependent). What you read hear may not be what you want to hear, but it is the truth.
You are putting your own life and freedom at great risk. It is only when I was forced to face my consequences, which included being homeless and getting locked up, that I even THOUGHT about quitting drugs. If someone had given me money, taken me to get drugs, given me a soft place to crash, I would still be using. Instead, I have over 20 months clean, and it took me 4 years to get that.
As long as he is using, you can count on your "relationship" getting worse. We A's (addicts) will do anything to get our drugs and that is our main concern. We hurt people, in some of the worst ways, and will use people to get what we want (drugs or money to get drugs). Even if we love someone, that love takes a distant back seat to our need for drugs. An A doesn't love themself...there's no way they can love someone else the way we should.
I hope you keep reading and posting. This place has literally saved my life.
Hugs and prayers!
Amy
