Hi Suzie, I am not a doctor or anything just some guy living in Italy with a step son who has been doing the same as your boyfriend for 12 years. You have a simple question to ask of yourself and your boyfriend, that is which is most important me, you or your coke? Spoken quietly in the cold light of dawn at the kitchen table with unblinking eyes. If he has the resolve or the basic human ability to recognize pure love he will understand you. Think of this there is a road with a crossroads one points to the left, you decide, love me and leave the crap behind, one points to the right embrace your dependency and leave me and all that you care for behind! I say this because i am facing the same situation with my step son who tonight is sleeping in his car having robbed me and my neighbors on Sunday night before running out to get a heroin fix and imagining he could have got home before we noticed, but as i went to check that he had not taken his Lorenzepam before bed I found that he had gone. Suzie we need to be firm. good luck and keeep me informed about how you get on. Chris from Italy
