A guy doesnt usually start hitting his girlfriend out of the blue — it generally starts after a history of verbal and emotional abuse; cutting her down, telling her she's fat or ugly, chipping away at her sense of self worth. Typically, by the time the physical violence begins, her self-esteem is seriously damaged. When she doesn't value herself, it is more likely that she'll accept and put up with the physical abuse. Once her self-esteem has been broken down, it can be even harder for her to leave the relationship.
