You were NOT stupid. You fell in love. Love is never stupid. It's just you fell in love with someone who is more in love with a drug...than people. I know in my heart that my ex loved me the best he knew how. And that he just didn't try hard enough or what to be clean enough to get out of the mess he has made of his own life. From the "recovering" addicts I have talked to....it is VERY tough to get & stay clean.
