Is it normal that he's so offended by this?
I'm a female, and I have a male friend. I definitely don't have feelings for him (maybe a little, in a purely physical and sexual way), but he and my best friend are together and I'm in a relationship. He's just a platonic friend.
Anyway, he and I have this thing where we're mean to each other. Just stupid, harmless things, like calling each other stupid or bitches, or trading insults that are obviously untrue (I have dark skin, so he likes calling me Indonesian or calling me a terrorist). This may sound weird, but we just like messing with each other.
Recently, I don't know how it started, it changed. We started saying really mean things to each other. Personal things. He said something really, really mean about my parents yesterday, and I retorted with my own insult, that ended with a loud "Jesus Christ, dude!"
Big mistake. He's very religious, and he immediately exploded, yelling at me for taking the name of his savior in vain. I forgot about how religious he was and immediately apologized, but he won't talk to me. I feel really bad about it — just because I don't share his beliefs doesn't mean I have to say things like that in front of him — and I just want things to go back to normal. I have apologized sincerely and I've cried from sheer guilt a few times, although not in front of him.
Is it normal for him to get so offended? Is it normal for me to feel so bad?
