Sometimes I can overthink BUT I don’t think so this time.

So about 2 nights ago I picked my bf up from work and we were joking in the car as usual he ALWAYS picked at my forehead size after getting my hair done so fast forward he compliments my hair and proceeds to say “your hair is nice but ya know it’s STILL not taking the SHINE away from your forehead 😂” so my response was “oh whatever asshole” which he always responds “that’s my middle name” BUT here’s the catch, his response after that was “well you’re a cunt” I just took a long pause after that and immediately got quiet and extremely agitated as a female i took that so personal but in his eyes it was a joke. Am I taking it too far? I just thought i was past that stage in relationships .. my last relationship ended bc of verbal and mental abuse and this particular moment just took me back there but I can’t seem to let it go. We have had disagreements before and i have dropped it but this time i can’t see myself just letting it go without a genuine apology.
