I've been dating this kid that I've known for almost 2 years now, for 5 months. I'm 18, and he's 17. He has been using opiates since 7th grade, it's been 5 years. He was addicted to oxys, did so many percs, and then started snorting heroin. He says he stopped heroin for a coupe months before and when we first started dating, I doubt, and recently picked it up again, probably because of his 'childhood brestfriend' that's also addicted to heroin, and shoots it. In the beginning of our relationship he said something about doing percs again because afterall opiates are his thing and I told him that's not what I signed up for I don't want to be with someone who does that **** and he said ok I wont, and then proceeded to lie to me for like 3 months. The past month I've noticed his pupils were constricted so often and when I asked he lied to my face countless times. When he eventually told me the truth, I cried and make him promise not to do it anymore. That happened about 3 times. The most recent time I was ready to break up with him but we worked things out with more promises, which the next day he breaks already snorting two bags of dope with his friend as his 'last time'. He's been supposedly clean for like a day almost two. The biggest issue is he doesn't see why heroin is bad at all. It's probably because he's been using them since the 7th grade, and he's become so used to it. That's a problem because in my eyes heroin is disgusting. He really thinks it's like a game, and that for him quitting will be easy (as long as he has percs to help him off) I'm afraid this is going to be a lifelong battle that I'm not sure I can stick by for. I've told him if he lies to me again I'm automatically done, but I wouldn't be surprised if I'm getting lied to right now. But I do love him and he chased me for a good year while I was messing around, and convinced me that he was completely in love with me, so it doesn't make sense how he could lie to me countless times, not to mention the infinite number of little lies to cover up his tracks. This whole situation ruined what to me was a great relationship that could've lasted, but now I feel depressed all the time, and I just want to cry. I don't know what to do..
