I don't think you do understand a bit about hospitals. Canada is a country with very good doctors and medical care, isolation units, sanitary practices, and the lot. It is not some backwater, third-world death-trap.
What could you possibly provide at home (other than access to crack) that is not better done at hospital by pros? You then say:
Somethings are complex and people who are codependent for addicts have much the same symptoms and sickness and codependents for acutely ill people who are not addicts.
OK, fair point, but all that means is that both codependent types are doing the same harm to themselves and to their ill partners, by not allowing them to hit bottom and be forced to allow professionals to help them.
We are not professionals, and we are not detached. We can't get them out of these situations in any way. We are not powerful enough. You seem to think that your emotions, your guilt, your love, your grief, your shame, are powerful enough to cure him. If that were true, none of us would be here.
We didn't cause this. We can't control this, We cannot cure this. All any of us can do is get out of the way before we are dragged along with it. Please, get to an Alanon meeting. You need help. And keep coming back here. None of us are blaming you. We know that you are sick, too.
Love,
KJ
