We shouldn’t victim blame, it truly can happy to anyone.
But there are often signs that people either don’t see or ignore. Low confidence, raised in an abusive home, innocently minded, financially or emotionally dependent, children etc - so many reasons why women may choose to downplay signs until you can’t deny them anymore, but can’t get out safely.
Girls need to be given the confidence to trust their instincts, to break up a relationship that doesn’t work for them (whatever the reason), and to demand a certain level of treatment and behaviour from their spouse.
Number one rule is to never stay if someone has hit you, even once. Never give a second chance. Never doubt yourself.
