<human>: I am all for self defense and all, but I do not tolerate those who hit unprovoked. And I am a pacifist, so I have never hit anybody in my entire life. 

Well yesterday night, I came to pick my boyfriend up from work because his car was still being serviced during that time and most of his friends were either asleep or at work themselves. But something work-related for me came up, and I was only able to come get him an hour later than I said I could. He seemed really annoyed when I told him over the phone, but he didn't complain.

Anyway, when he got in the car, he was smiling at me. But not the happy kind of smiling, but the passive-aggressive kind of smile that people make when they're pissed or agitated. And once he got seated and buckled up, he hit my arm REALLY hard. And it wasn't even the type of hitting that was playful or uninentionally painful, because he didn't do it once---- he did it multiple times, LOUDLY. Perhaps it was more like a very hard spank on the arm, but it hurt regardless. It made my arm red and the pain lasted 10-20 minutes each. He really MEANT for it to hurt. 

But when I kept telling him that it was painful, he only laughed and told me that it was okay since he's never hit me before. 

So since then I haven't really felt like talking to him and he seems to be acting pretty normal, as if he'd done nothing wrong. Am I feeling bad about this over nothing, or could this become a problem in the long run?

<bot>: Last night my boyfriend hit me multiple times for fun and sees no problem with it, and that bothers me very much.
