Is he really sick, or just blowing me off?

A guy messaged me on Match.com on Sunday, and we talked on and off all day. He asked me to go out on a date this Thursday. We talked again Monday, and on Tuesday, I only heard from him once that morning. He seemed really interested in me on Sunday and Monday. I sent him a text Tuesday night, but he never responded. I sent him a text tonight (Wednesday), and asked if something was wrong. He said that he had been sick and that he wasn't going to be able to make our date tomorrow. I guess it's just my first instinct to think that he's blowing me off. I asked him if I said something to change his mind, and he said no, not at all. I don't know what to do. I guess just wait and see if he ever texts me again. What do y'all think?
