Look on thehotline.org website for your state's domestic violence victim support groups, or contact the police and ask them for the information. They have not only the resources to help you get out of this relationship, but also a group of people who will support you and be there for you throughout.
then you should seek out a community- for instance, the Universalist church is welcoming to all, and made up of very nice people. You don't have to be alone, and you certainly don't have to be with this abuser. But do know the human mind has a coping mechanism that causes far too many partners to stay with an abuser, so this is typical and not just you.
You don't have to be alone,and you don't have to put up with abuse.
Please go ask for help.
