Hello and welcome to SR. Sorry for what has brought you here. I'm an opiate addict in recovery. I know it's frustrating for family. My husband was ready to walk out with my kids when I finally decided to get serious about my addiction.
I think the fact that your wife has you to support her financially (assuming that's the case) is keeping her from taking a serious move toward recovery. It did me. Like I said I finally got serious when I realized I might be losing my loved ones And would soon be out on the street. Has your wife tried the Suboxone route? That medicine has saved my life. It took me out of active addiction long enough to attend an IOP and learn some tools to get me thru the intense cravings. Also, helped me to address some mental health issues that I was using my DOC to self-medicate.
It could be that your wife has some mental health problems too....that are being left untreated. It's very common for addicts to have unresolved issues and use drugs to get rid of symptoms or to avoid uncomfortable emotions.
Whatever is happening here...living a life with an addict in active addiction is horrible. Addicts...especially opiate addicts are on a roller coaster ride....to Hell. They are in a perpetual cycle of chasing their high. They will go to great lengths to get a hold of their DOC. Their lives become consumed with finding the money....to pay for their drug....they lie....steal....cheat....sell all their possessions....for one hit of H. I know I was caught up in that cycle. I even went so much as to cheat on my husband......hook-up with a man that became my biggest enabler....giving me his weekly checks to use and searching for connections....dealers he could buy my drugs from....just to keep me tied to him. I assume he became addicted to me.....using me as much as I was using him. Not the right type of relationship. Make sure you do not get wrapped up in that type of relationship. Because addicts will use and abuse their enablers....just to feed their addiction. My husband was not my enabler....which is why I sought outside help. At first he was.....unknowingly. I would take grocery and bill money to use for my drugs....then I started selling everything I owned of value....even my wedding rings. Nothing was too valuable or sentimental.....when it came to my drugs. When an addict is on active addiction....there is only one thought....the drugs. It is a drive that is so strong and primal....as strong as our drive to live......it actually overrides our drive to stay alive.....which is why so many addicts out themselves in serious danger....risking their lives to attain their DOC as well as taking too much of the drug that they OD.
Your wife's addiction is very serious....if left untreated she could die from it! Like they say there are only three places that addicts will ultimately end up jails, institutions or death!
The best advice I can give you is make sure you are not unwittingly her enabler......she should not have access to your money, bank account, or credit cards.....Or anything of value...that she could sell and get money for. She should not have a cell phone....at least one that you pay for and she should not have access to transportation....such as a car....that you are paying for or putting gas into. Those three things are used in acquiring the drugs....without those it makes it very hard to arrange a deal. Not impossible as there are ways around those things....but that's on her....not you.
There are some good articles in the secular family side of this forum about craft methods.....learning how to talk to your addict loved one.....a book called How to get your loved one sober is also packed with good information.
Good luck to you.
