This is most likely, I think, because he's sensed a change in you, and he's trying to reassert dominance.
I would bet anything that for him, the enjoyment isn't in the penetration or the climax at all, it's in the fact that he's forcing you to submit to and pretend to like your own debasement and humiliation. He knows you don't like it, and that's what he loves.
As you've begun to show signs of pulling away from him, it seems he's escalating the roughness and dehumanising aspects of the rapes to try to make a point – 'I still control you. You'll do whatever I want. I can do whatever I want to you whether you like it or not, and you'll take it – and we both know it."
It's about reinforcing the grooming he's enacted on you; to be afraid, to obey, and to know that saying 'no' to him, or doing anything that upsets him, is too dangerous. That's why he punches the wall, or throws things – it's a deliberate show of dominance and intimidation, to scare you into submitting.
It seems as though your whole life revolves around making sure he's happy above all else, because otherwise, bad things that are too scary for you to contemplate might happen. You're essentially living in a prison, trying to please your own rapist, and it makes me so sad for you.
