Hello Bwanawill,
I can't tell you what to do, I've learned it's best to just talk about my own experience.
I did a 28 day stay last Dec. for prescription pain meds. I had to detox and I could not do it at home. I was prescribed so much my wife was concerned they would find me dead from an OD. My wife made it clear to me that the two children that are still at home where her/our first priority. This became my main motivation to stick out rehab and the intense withdrawal.
So for us, our children came first. As an adult in the equation, I had to deal with the results of my actions, the kids shouldn't have to deal with my bad decisions.
My wife told me that if I didn't go to rehab and get clean she would have to get the kids away from me because the way things were, it was toxic for them.
She's a great Mother, great priorities - kids even before me. I had to agree and I'm through it, we're all together and things are going pretty good.
