What does it mean if a guy send you a text that says "Hey" and that's it?

I hung out with this guy the other day and didn't think he seemed terribly interested.

But the next day he sent me a text and all it said was "Hey."

We texted back and forth maybe 2 more times about what we were up to. That was it.

Meaning?
