Hey I've been in this situation. My husband is a now recovered opiate addict. (I saw opiate because it started as pills and ended with heroin)

I remember finding his hidden stashes of paraphernalia (syringes, spoons, little cotton balls) and he said they were from before which at the time I for some reason believed. There were a lot of little things that looking back on were a giant neon sign flashing "drug addict". I mean he was a functional addict, but one none the less. I remember when he drained our savings account right before he came and told me he was going into out patient treatment and starting methadone. I remember getting into an almost fist fight on the floor with him because I had his phone and I fucking knew he had a dealers number and he knew I knew and would rather roll around on the floor prying a phone from my hand then admit he had fucked up. Vacations we're planned around where he could guest dose, trips cut short because he forgot a dose. I will not sugar coat this, our lives sucked for about two or three years. Just a god damn shit show. What up no sex for like three years. There are countless stories from before treatment as well. Things that now looking back are so fucking stereotypical of a user and an addict.

Why I stayed I still don't know and I can't begin to describe. We are in a much better place. My husband is off methadone. He has actually acquired a good set of coping skills and confronted his ptsd and in the past month or so has entertained the notion of even telling family and friends his history of addiction. (Yeah we even did this in private. People just knew we were broke because of therapy and his "medication")

You need to look at this from a very cold and detached point of view. Yeah, we have a success story, but he also has four or five dead friends/acquaintances from heroin. I would not stay unless you really feel like he wants to change and even then only deal with that shit if you feel like you're going to be with him for the long haul. Shit we were engaged when this all came to a head. A two year relationship? I don't know. I just don't know.
