I have a friend that was clean for about 2 1/2 years and about 6 months ago I saw a change in his behavior. Our conversations became less and less.He moved to his home town and got mixed up with the old crowd. I heard from him the other night for the first time in about 2 months. I never would have imagined it had gotten this bad. I never ask if he was using again but I know in my heart the answer. We even had a conversation the other night and he got so angry over nothing he told me he hated my guts. I know its not the real him talking. I don't know what to do? How do I handle this? I don't want to turn my back on him. I know that I can't force him to want to get help but it breaks my heart. I love him dearly.
