city of refuge

I need a "city of refuge"....a place where my husband can't go.  Or won't go.
You know?  Like in the Bible where people fled when they did something or were suspected of doing something and they were safe there.
I realized that my stress is that there is nowhere in my life and nobody that he doesn't have and utilize access.  Hmmm.  I'll have to figure out how to fix that.
grace.
