What does he mean by “Not right now” Is he implying there’s a maybe he could love me again?

Him: Go get your back blown out like the whore you are you deserve it
Me: You love me don’t lie
Him: I don’t love you, I use to not right now
Me: Not right now? Ooo! Right now.. Okay”
Him: Fuck you” *hangs up*

Short summary. That is my ex and we broke up. I think I hurt him emotionally by sleeping with someone else (Me and him WERE NOT together at the time) no that doesn’t really make a difference, but he did tell me he wanted nothing to do with me so I tried to move on.
