Should I be worried?

I met this really nice guy online, and we started talking a month ago. We would talk on the phone for 3 hours, and text each other every day. He’s 2 hours away, and we were supposed to meet weeks ago- I canceled cause it seemed so sudden. Last weekend he had a family emergency, and we couldn’t get together. This weekend I haven’t heard anything from him since late yesterday. Do you think he just gave up on me? Or just isn’t interested?
