I think I would look into going to a women's shelter for awhile if possible.
They usually have excellent security and from there you can look for work
and a place to live. If you have no money or job, it may take some time
to save up. Could you possibly move back to parents / family for a bit?
I'd also change my phone number and break all ties from him as others have suggested,
Leaving for the last time is the most dangerous as Ann said. Be very careful.
