You stated that you have NO background on dealing with addicts. Let me help you. It would be safe to say that he has destroyed all trust in him, correct? So,...you should atleast know by now that you can not ever trust the word of an active addict, and must be very wary of the word of an addict in early recovery. He has lied to you many times in the past to get you to believe that he is clean or getting clean or serious about getting clean. Ive done that, and every other addict on this site at one point has done that. Its par for the course. He needs to prove to you that he means it and the ONLY way to do that is for him to rack up MAJOR clean time. You must do yourself AND him a favor and NOT see him during this time frame. Hes got to prove that getting you back isnt his reason for getting clean. It MUST be for himself. Doing it for any other reason will send him back out once he obtains what he was after.
