<human>: So I got in an argument this weekend with my SO of a year. It wasn't really anything huge, just tired people being grumpy. I was kind of a bitch to him. We were trying to stay up to wait for something and I didn't want to be awake anymore so I eventually said "Fuck this, I am going to fucking bed", etc. He was already angry, saying stuff like "I just want to strangle you", etc.

Shortly after I went into my bed he ran into the room very aggressively and smacked me on the rear. Not in a playful way, but in a mean way. Then he rushed over me and made me stare him in the face while he told me to stop being a bitch.

I've been in abusive relationships in the past, so I tried explaining to him why this makes me really uncomfortable and brings back lots of old feelings. He doesn't feel apologetic and remorse over it, and he said that if I didn't want to get smacked then I should stop being a bitch.
I'm not sure how I am supposed to go on about this, or what I should do to make him see why it's not a good idea.

Give me the gist of the text in a nutshell
<bot>: Got in petty argument, I was a bitch, got smacked for it, he won't apologize and says I deserve it for being a bitch.
