Should I call a man I've been on a few dates with tonight?

We dated for a few weeks. I saw him last, a week and a half ago. He claimed he wanted to see me again, but he hasn’t made contact despite the fact that I’ve called him once. Should I try once more today, if not, when? Should I accept it’s done? Even if he’s done, I’d like to at least say goodbye, or even learn what happened.
