I am very sorry for your pain but there are statistics you should know. Less then 3% of crack addicts recover for life. (some say less) Also, less then 10% of addicts recover life. Cynical One has lots of great information about Crack addiction in her blog.
You won't be able to keep ignoring it. It will progress. You are young, with a bright future ahead of you, please seek some kind of counseling to figure this out and why you are settling for less then you deserve or you may continue to pick the same kind of partners over and over again.
Get healthy now while you are young so your future is bright. I so wish I had!
