<human>: Can you succinctly summarize the text in 1-3 sentences?

I am a female (23) and I have gone out on one date with a guy (27). After our first date, he texted me the next day. The day after, he called just to say hi. A couple of days went by, and we text flirted back and forth. Then he went MIA for a couple of days, so I texted him saying hi. He said "Hey! Was just thinking about you! Miss you" Then he told me we should have another date. He asked me for Monday, but I'm working late, so I said I can't, how about Wednesday? It's been 2 days since I sent that. What gives? Should I say something to him, or just delete his number? I kinda want to know what happened.
