Why would a guy start texting less, but then set-up a first date?

This is the SECOND time where a guy would start texting me throughout the day. Then a few days later, he would start texting me less and less. Next, he surprisingly set-ups a date, and follows through fine.

Why do some guys do this odd behavior? This is the second this is happening to me.
