I knew has was an alcoholic, or at least that he was drinking far too much. I also knew that he had taken heroin in the past, and I thought it was years ago. he said it was somewhere he would never go again. I was naive.
I let him know I was not interested in a relationship with someone who drank that much. He quit drinking for 8 months.
Shortly after that I married him. I had a suspicion that just sober wasn't enough, that he needed to be in recovery, and to me that was working some kind of program, but he said he had it handled. I doubted myself, thinking 'perhaps he knows best about his own recovery, we are all individuals'
1.5 years after being married he was using heroin - he picked up again - and it turned out his clean time was questionable.
