Is he a Narcissist?

Beyond frustrated with my ex-husband who happens to be my current boyfriend. We have been trying to work things out after the dissolution of our marriage. He says things to me that are extremely rude and judging of my body. Today, in particular, we got into an argument about his lack of desire and attraction for me. From my perspective, he does not desire me nor is he attracted to me. Long story short, he has cheated multiple times, multiple people, and he did it for 5 years straight without my knowing. That's a huge hit to my confidence and it would just feel nice if he gave me a compliment sometimes regarding my body. Well, today, he says to me "I am attracted to you, not your body". He meant it to say he is attracted to my mind, but he does not find my body attractive. A couple hours later when I asked for clarification, he then says "I do not find your body desirable. You do not take care of it". He then twists what I say when I tell him there are millions of people on this earth, he is but one. He twisted what I said and said "well, if there are millions of people that will treat you better, then you don't need me". And stops talking to me for a while. How did he become the victim?
