Excluding an emergency (death in family, serious illness/accident, etc.), when a guy alludes to getting together “soon, Thursday night, this weekend,‘ etc. and says he’ll call then doesn’t, he’s just not that interested and/or used OP as a backup (probably one of several). In retrospect, I'm not sure the terminology/label matters that much. The outcome is the same - he didn't come thru.
While I understand the disappointment, I got the impression OP and this guy had never even met. The OP asked about sending him a "Thanks for wasting my time" message. I say "No", move on.
