There's also the added fact. That in a majority of the cases, women are abused by family and close friends. Imagine reporting it and having your whole or part of your family turn against you because you're tearing them apart. It's much easier to report an abuse if it's by some unknown guy or even an associate. But if it's a family member, it's like a personal betrayal against them (not even acknowledging their betrayal against you).
And to a lot of people. In that case, it's just not worth destroying your family.
