Anyone have a boyfriend/girlfriend who uses drugs, mainly heroin and it is slowly ruining your relationship?

This was asked a while ago, but I will answer in case anyone needs a good response to this kind of question.

The answer is no, not anymore. I can say from experience that you cannot have any kind of healthy relationship with a heroin addict because he or she will always love heroin way more than you. Heroin is is special like that. It literally rewires the brain so that the addict's primary goal in life is to seek and secure heroin - and if friends and loved ones become casualties along the way, then so be it. Heroin always matters first and foremost. The heroin addict will steal your grandmother's pearls just to get a fix and then lie about it to your tear-soaked face. (The addict will also make sure to help you look for those precious pearls.) They are master lyers and manipulators, and that kind of dishonesty and downright criminal activity has no place in a relationship. I dated a heroin addict (unknowingly) for about a year until I got a call from the bank one day informing me that he had stolen my checkbook. And it didn't end there: I found out that he had used my credit cards and gotten a hold of my atm card and pin number; then I learned that he had stolen my jewelry, clothes, ipod, video camera, and countless other things from my room. (I thought there had been a break-in when I noticed things go missing, but I realized that it was just my heroin addict boyfriend all along.) Of course, he denied all of it and assured me that he loved me and would never do such a thing. This is the game they play, and they are very, very good at it.

Simply put, lies, manipulation and theft is what you're in for if you continue a relationship with a heroin addict. And what the hell kind of relationship is that? Do you really want to spend the rest of your life clinging to your purse, locking up your valuables, and worrying about whether you're being lied to? And what about family and friends? Will you be able to bear the pain when your heroin addict lover steals your father's rolex or something shiny from your friend's living room? Even if the heroin addict does get clean, you will never be able to rebuild any kind of trust with this person, and of course, there is always the extreme likelihood of relapsing. Stay with a heroin addict, and a long life of pain and hardship awaits. It's not worth it. He or she is not worth it.

When my ex's heroin addiction came to light, all of my family and friends told me to cut my losses and run. At first, I didn't want to listen because I was somehow still in love, and thought maybe there was something worth fighting for in this person. It was only after I learned that all of my roommate's fine jewelry had mysteriously gone missing that I finally got the wakeup call I needed to end the relationship and wipe my hands clean of the heroin addict in my life. It was the best and most important decision I ever made. 

Run.

I was in a relationship like that a few years ago. He was addicted to oxy, he abued me, he stole form his work, from me, and his dying grandmother. He lied to everyone. He went to jail many times. I finially got up the guts to leave him after the cops got involved.
Leave now.
