Is it normal for a girl to have anger issues from previous relationships and taking it out on her current guy?

Her ex sexually abused her and often pressured her to do against her will which fucked her up and gave her trauma. She didn’t work on this much before she met me but she is extremely abusive she has hit me she has hit our dog but when someone says she might have mental health issues she calls it gaslighting
