Do you respond when “ghosts” re-emerge?

Had a fun naked time with a boy [28 year old man for those desiring clarification] about 6 months ago. We texted with eachother right after and said how much fun we (both) had and how we couldn’t wait for round 2. Cool.

Fast forward a couple of weeks, I try to set something up, he says yes but is less enthusiastic. He cancels while I’m in a cab en route to his place because he “has plans with a co-worker”, then goes quiet altogether.

Today, 5 months later out of the blue, I get a message from the ghost wanting to meet up soon. No acknowledgement of the last event.

I’m hesitating about whether to respond. On the one hand, he’s hot and it was fun. On the other, it did hurt my feelings a little to get thrown away like that, and we all need to have some self respect. What would you do?
