Fights

I just got in a fight with this guy I'v been talking to for a while, we would have a date tomorow and he told me he had to cancel last minute, so I said it was okay (although I was anoyed by him not telling me why because I was afraid he got bored of me), Minutes later he told me he was kidding and I told him that I had told my other friend that he canceled and that I could meet up with her. He told me not to take everything so serious and I told him I tend to do that because my aniety makes me think in worst case senario's. On witch he said that I shouldn't be stupid and that just broke me so I freaked out and now we're in a fight. what should I do?
