why not let him work his program and revisit dating him in a year or more?....I speak from experience...mine was clean for over a year, and it turned for horrible twice, and the second time was the last time. Heroin is a total nightmare. You realize that the person you loved, might not have ever been what you thought he was. Think about other things like hepatitis, HIV, etc. etc. etc. Addicts lie, that's just what they do. Addicts lie, cheat, steal etc. If you are not prepared to deal with all of the horrible things that come along with addiction...get out now. We were told that it's a progressive disease, and boy did it ever progress.
