I am going to give you the same exact advice I gave to V last week. I am concerned for your well-being and you do need to be completely safe from H. Not sure if this is the first incident or not. No matter.
Can you go to the nearest women's shelter and stay for a while? In the States, a woman is allowed to stay in a shelter for at least 30 days. Not sure about the UK.
I do think you need to remove yourself from this place to get some distance between you two and gain some perspective of your situation from the outside.
It's kinda hard fighting a raging fire if you are standing in the dab smack middle of it.
