i doubt she has to worry about being abused again.
the whole point of child and/or spousal abuse is that the person being abused is too small or weak, physically or emotionally, to defend themselves. that's why abusive parents beat up their kids when they're small and stop once they're big enough to hit back.
i think 18 or 19 is a bit too big for even the stupidest parent to think about hitting their child.
i wouldn't worry about bringing pepper spray or whatever. just be ready for any psychological trauma.
