So i’m a senior in hs and my bf and I have been together for a bit over a year. We have a habit of jokingly calling each other names when one of us does smth for the other. Whore, slut, bottom, bitch, and such. We both consent and find it funny. However today after he did smth for me at lunch I called him a slut, which he does to me too, and he slapped me semi-hard across my face. I couldn’t tell his expression cuz my friend sitting next to me immediately grabbed me and pulled me into them and told him he can’t do that. When we left for him to walk me to class he told me “You know id never do that for real, right?” and that it was ok cuz i was into it (that part i think was a joke too) and I told him it was ok since he wasn’t mad and he said he definitely wasn’t mad. It didn’t hurt for too long, just like 5 mins i could still feel it, but i was shocked. This isn’t the first time he’s been semi-violent but I don’t really wanna get into details about those. We’ve discussed those and stuff. So just based on this, was it ok? Or should I be worried?

Btw thank you to anyone who has read this and if you’ve voted, I appreciate it. I’m 17 and really need advice.
