I am sorry to here about your situation, but I want you to know that you are not alone, Your signifigant other will probably hit again, even if he has just hit you once. I would like to recomend that you talk to a support group that is in your area. I am an advocate for what is called the Valley Trauma center, and we deal with people who are in a abusive relationship. You must remember that you don't deserve to get treated the way you are.
I would be happy to give you referrals if you want them.

P.S. The above is my wife writting
