I just remembered this thread after posting a very concrete example of a boundary I put in place.

My husband didn't want to go through detox in a hospital before rehab, and his family doctor seemed to think he could do it at home. I told my husband that I was not going to be his 24/7 nurse while he detoxed.
If AH decided to detox at home, then I was going to take the dogs and go away for a week.
That was my boundary, and I was fully prepared and able to go through with it.
AH has ended up hospital and is now going through a medically supervised detox. But there was absolutely no doubt that I was going to do it.
