My biggest advice to any DV victims reading this, is to trust your instincts and make a plan. Contact womens aid, look in to the Freedom Programme.
Lots of people will judge, but then you are used to that. Lots will tell you what you should of done, or should do, but they are not living your life and don't necessarily see that it is a life and death decision.
Connect with dv groups, grow your network. Have an escape bag.
For me, I called the police, they didn't arrest him because they didn't want to make my situation worse, as I was already in danger. So they left me and reported to SS. At that time SS did nothing as only I was raped. It didn't matter that he had pissed on his kids or cut himself in their beds. The school even commented that his rapist self was a better parent than my traumatized raped pregnant self.
So yeah, its easy to blame the woman.
Make a support network and tell the police, use the network to help you get out safely. Don't try doing this alone, it took me 7 years and I am still trying to recover from the trauma of SS involvement.
Other victims are out there, they will help you find support. They will help you be safe. We understand.
