I'm 27. My husband's DOC is oxys. Its a terrible addiction, and that's great that your AH is getting help-- mine only threatens treatment when he becomes fearful that I might actually leave, but he never follows through.
Now, what are you going to do for yourself? I've found AlAnon very helpful, as well as spending time with supportive friends (unfortunately, all friends are not created equal, and some of them you can turn to with problems like these, and some of them just don't "get it"). I felt very alone for the two years our lives spiraled out of control, and now I know that I'm not alone, and no matter what, I'll be okay.
