He wants to take his anger out on my body: that's not okay, right?

My ex-boyfriend and I are working through a very hard situation where in his perspective I cheated on him so I'm trying to fix things and gain his trust again. There has been a lot of pain and distrust between us lately but we are finally getting to a healthier, better place. However, he said something that really disturbed me the other day and I need someone else's perspective....
