I think there's a huge possibility that one day soon you will suddenly decide to go. I would've gone sooner if someone had took me away and helped me, but of course I wasn't telling anyone my problems, I know he had control over his temper because he never displayed it front of anyone, he controlled the finances too, I had no independence
I ran to my friends the day after he fractured my cheekbone and almost finished me by strangling me, there were other injuries, but that day she said if I didn't tell my family, she would, so I had to fess up, that's when I got the strength to leave, it was painful because during peaceful phases he was nice, but I learned so much after breaking free just how controlling he was, and didn't realise it at the time
I'm sure you too will have your time to leave if he carries on without getting the help
Take care
