It takes a real douche bag to hit a woman, and this man is obviously a douche bag. However, unfortunately for him, her brother wasn’t having any of it.
After this man had struck his wife before, her brother warned him that if it happened again, he’d beat his ass. I guess he didn’t believe him, so he did it, and alas, he got his ass beat by her brother.
Seriously though, women. If you get hit the first time, you are a victim. But if it happens again, you’re an accomplice for going back in the first place.
