Am I just sensitive

I’ve been talking to this guy on Tinder for a week now and we were talking about the zoo and he said this.

I had a few mental breakdowns today so I don’t know whether I’m reading into it too much and took it to heart or if it was just a joke or weather he actually is just one of them types of guys who says jt and means it. 

Idk if it’s just lighthearted jokes or if I’m trying to make excuses

And also, how do I reply?? Like idkkk
