Should I call my boyfriend?

Yesterday, my boyfriend got mad at somehing I said. Later that day, I asked why he got mad. He did not answer. The next day he texted me if he owed me any money and that he feels uncomfortable that I always pay for the things we do. I replied and we texted for a while. And that was it. Normally, he calls me everyday but for the last 2 day he hasn't called me once. Should I call him or should I give him some space?
