Is this narcissim?

My bf and I got in a argument.. he got angry and started choking me and hitting me to the point I couldn't breath.... then he started blaming saying that I took him to to that point and he shouldnt be with me coz I took him to that point.. just kept blaming me for what he did. And this isn't the 1st time he's done that.

I showed him that he scratched me and that I'm bleeding.... he said he didn't care and never once apologized. Yesterday I txted him my whole body hurts.. and he compltely ignored that part of the txt.

I just don't know what to do and why I'm still here.
