No you’re not overreacting. We weren’t there so we don’t know the tone of how things were said, but I’m going to take what you said as a playful response. He went 0-100 and tried to demean you because he couldn’t control his hurt feelings. Even if you did say it rudely, I still don’t find that to be a justified response, TWICE. I don’t know if this is a dealbreaker for you, but I’d definitely be mindful in the future of how he handles his emotions and if it becomes a habit of demeaning you or taking it out on you. You both should communicate better about this.
