In my particular state, I was told in order to receive a wage to be my husband's full-time caregiver, we would have to do two things: A) get a divorce B) live in separate homes. I really never thought that made much sense. Perhaps, your situation is different. The link below offers some good places to start if you find yourself caring for a loved one.
This site is wonderful for anyone who is a caregiver. Great information and support, so please feel free to visit them.
