How do you feel if your bf say he doesnt feel like meeting you today?

We have a bit of disagreement and we are supposed to meet today, then he suddenly texted that he doesn't feel like meeting today. What should I say in this case? In the past, for similar situation, we still meet and we kept silent the whole time and dragged until we finally talked/argue things out, but it was tiring and emotionally draining the whole time.
