Hi... I am new here, but I thought I could offer you some advice.
I AM that husband. I have been clean for 6 months. My wife nearly divorced me for my issues. Here's what I'd advise for u guys:
-He should find a good doctor that will keep him on Suboxone for 6months-1year. He needs time to get away from the dope, time for his mind to forget the need for a "fix". By taking suboxone every day at the same time, like a vitamin, he will start to lose his psychic dependence, a good thing. If you can administer the suboxone, that would be best, so he can't sell it.
-Drug test him, every 3rd day, or twice a week at the least. Get a box of those easy-test strips. We used "iScreen" brand. THey are good, I got busted for using and I had been clean for 3 days.. it still got me. Tell him that you are only trying to help, and that this will be the only way that you can trust him to stay clean. If you don't test him, he will probably sell his suboxone to get H. It is very common.
-NA meetings. Make him go to them, at least 3 times a week at first. after a few months, maybe down to once a week. Even if he doesn't like it, make him go. Even if he is an atheist (I am an atheist and I still did NA), make him go. He must have support from other addicts, it helps A LOT, more than anything else, I would say.
-Be compassionate, but firm. Make him see that there are consequences to his using. If he continually relapses, you must be ready to leave him.. this is one of the only ultimatums that work in addiction, the threat of losing a lover.
-Get him a therapist, 1-on-1 counselling will do him the most good, but some people do well with group therapy. I get my group therapy at NA and I see a therapist for 1-on-1. Make sure it is a drug-addiction specialist.
Basically, think of it like this: He has a FATAL disease, like cancer or diabetes. He WILL DIE unless he gets the proper treatment. If you love him, you must help him get this treatment. If he refuses to accept treatment, he is choosing death, and you have no business being with someone that is committing suicide.
One last thing, and this is only my personal opinion. Take some acid... LSD... and talk it out. Talk about why he is using... how it feels and talk about how it makes YOU feel to see him use. Psychedelics have been shown to lessen the cravings for opiates BIG TIME. I personally tried to get clean for 4 years with no luck, then I took some LSD and really cracked the nut, so-to-speak. I tripped about 3 times over the course of 2 months into my detox, and I honestly say that it did more for me than ANYTHING else I have ever attempted in recovery. This is totally against NA mentality, but they don't know everything. In fact, if you ignore EVERYTHING else that I have written here, take this one piece of advice and TRY SOME LSD for recovery. It is a miracle worker. Believe me.
Good luck... this too shall pass.
