Do not tell anyone except people you can trust as being faithful to you and not at all to him. Friends or family of yours who are really close to you n hate him (if you have any left by now - usually the first thing abusers do is separate these people from their victim), therapist, domestic violence center, police (only if you have evidence to back you up with police or they will do nothing). Make a "go bag" and hide it in a place he will not find it. This should include one or two change of clothes, any medicine, any important documents (legals documents , anything with your social security number on it, birth certificate, any bills in your name, important phone numbers), make an "exit plan" - when would be the best time to leave? (preferably when he is not around or will not see you), how will you leave? (method of travel-if by vehicle be sure to get extra keys made at some point), what route will you take?, where will you go? who n how will you contact during all this?

Every step is important n it is very important you remain in contact with the person you will be leaving to so they know what your situation is and when to expect you. If you get in trouble during your escape call the cops immediately. If you are running to a domestic shelter they will tell you where to meet them. If something happens along the way call them asap.
